Can't say that I didn't cheat on this one- I actually found more than 4 players (the list had more than 10)- here are the 5 most recent according to what I found:
Alfie Conn (Rangers 1968–1974, Celtic 1977–1979)
Maurice Johnston (Celtic 1984–1987, Rangers 1989–1992)
Steven Pressley (Rangers 1990–1994, Celtic 2006–2008)
Mark Brown (Rangers 1999–2001, Celtic 2007–2010)
Kenny Miller (Rangers 2000–2001, Celtic 2006–2007, Rangers 2008–2011)

Not sure on the brown answer, maybe greatscot could clarify that one, maybe he moved between the two clubs, but maybe he never got to play an actual game for one of them, or either, who knows.
Great bit of googling sam.... Lol

Hey, I should get bonus points for supporting the Blue side of the Old Firm...

Yeah Mark Brown was a back up to Arthur Boruc, but he definitely played for both clubs!

Did he actually turn out for the gers john? , I don't remember him at all

Perhaps 1970 I know Gerd Muller scored two tricks in the group stages. And I wouldn't be surprised if a Brasilian bagged one in that tournament. England were also strong in that tournament, don't know if they had an attacker to do it though. Did Eusebio play in Mexico, I know he had a game with four in 66 scoring nine in the tourney

Nice guess, but incorrect...

Well google aided me a little bit, but apparently Sándor Kocsis scored 7 or so hat tricks for Hungary. And he scored more than one of those in the 1954 world cup in switzerland, so I'll go with that

Go with...

The 1954 World Cup where Kocsis scored two hat tricks?

Correct ManUK.... The 1954 WC in Switzerland is the right answer- a total of EIGHT hat-tricks were scored in that WC, with Koscsis scoring 2 for the high-scoring Hungary team:

Sándor Kocsis 3 goals Hungary 9–0 South Korea First round
Erich Probst 3 goals Austria 5–0 Czechoslovakia First round
Carlos Borges 3 goals Uruguay 7–0 Scotland First round
Sándor Kocsis 4 goals Hungary 8–3 West Germany First round
Burhan Sargın 3 goals Turkey 7–0 South Korea First round
Max Morlock 3 goals West Germany 7–2 Turkey First round
Theodor Wagner 3 goals Austria 7–5 Switzerland Quarter-final
Josef Hügi 3 goals Switzerland 5–7 Austria Quarter-final

The tournament also set the record for most goals per match in a tournament at 5. 38 (where were the goalies?) goals per game

Holy Mackrel, 5. 38

Nice one Sam, 5+ goals a game, would have been fun to watch hahhaa

Shay Given

Santa cruz?

Yeah i'll go with Shay Given

Everybody?

Shawn Wright Philips?

Maybe both Given and Santa Cruz did

Shay Given is correct, not sure about Santa Cruz but I think its true

Baggio

Not many player who won the U-23 European Footballer of the Year award played in 3 world sups

Yeah, gave too many clues on that one.... Anyway, yes Baggio is indeed correct

God bless bud, cheers

Tony Adam?

Yup. He made 669 appearances from 83-02

I'm going for: Ajax Juventus Liverpool and Nottenham Forrest

Manchester united 99 and 2009. Barcelona 2009, inter milan 2010

Barcelona 09 lost a game or two in the group stages after they sealed qualification, forget against who and Inter in 2010 lost to Barcelona away at Camp Nou 1-0 thanks to a Pique goal.

Just a stab in the dark, Liverpool, Milan, United and Ajax

It was 2-0. Pique and Pedro

Nope it was 1-0 just Pique. Bojan scored the 2nd one but it was disallowed. I got nightmares about it. 100% positive. We lost the first tie 3-1. In that match Pedro scored

As mentioned, only 4 teams have been able to accomplish this feat twice:
Ajax had 7 wins and 2 draws in 1971–72 and 7 wins and 4 draws in 1994–95
Liverpool had 6 wins and 3 draws in 1980–81 and 7 wins and 2 draws in 1983–84
Milan had 5 wins and 4 draws in 1988–89 and 7 wins and 5 draws in 1993–94
Manchester United had 5 wins and 6 draws in 1998–99 and 9 wins and 4 draws in 2007–08

Nice I got them all

Zdenek Zeman!    Attack, attack, attack!Mad respect, total legend

I think its liverpool

Barcelona. I don't think they won it under the name UEFA Cup though  

Liverpool

Barcelona won the UEFA Cup Winners' Cup against PSG at The Kuip stadium, Ronaldo scoring from the penalty spot. Crazy atmosphere.

Dunno if they won the UEFA Cup though

Clue: The question said teamS.... Not just one team

Liverpool, Barcelona, and Celtic?

Liverpool Barcelona

The uefa cup/europa league was the former cup winners cup, so man utd must be one, unless you mean someone won the cup winners cup, champions league, and the NOW europa cup, if that's the case, skip united.... Lol
We need clarification.... Lol, do you mean they won 3 seperate trophies?
As I count the europa league as the old cup winners cup, and therefore the same competition

I think Ajax, Bayern Munich, and Juventus are the only 3 teams that have won all 3 tournaments

Yeah it is kind of confusing but I assume which teams have won it under the numerous different titles

Yeah, under the titles given, Joseph911 is right- just 3 teams have won all three: Ajax, Bayern Munich and Juventus

Patrick Kluivert

Good guess but no dice my friend

Dennis Bergkamp?

Your question isn't very clear, if you are looking for who scored the most World Cup goals for The Netherlands in 1 world cup then the answer is 5 goals and that was accomplished 3 different times, Johan Neeskens in 1974, Rob Rensenbrink in 1978, and Wesley Sneijder in 2010. If you want to know who has the most all time World Cup goals for The Netherlands then the answer is Johnny Rep, he scored 7 goals, 4 in 1974 and 3 in 1978

Ya I was talking about career goals, and Rep is correct. You either have a tremendous knowledge of footballing history haha or you are getting a little help from your friends aka the internets. It's all good man, just try and use your knowledge and not use google or wikpedia cheers, if you didn't use that, I apologize and cheers for the footballing knowledge you possess

Martin Buchan played for Aberdeen, Manchester United, Oldham and Scotland between 1965-1985 and currently works for the PFA in London

Correct Joseph911

Many of them will remember him, Charisteas...

Correct again!

Charisteas scored the goal in the 57th minute

Let me think 98? No they lost to Argentina. Quarters in 86, but I think it was 1970 when they lost to West Germany in the semifinals

I think four times in quarter finals: 1970, 1986, 2002 and 2006.  

Nope

They finished fourth in 1990 world cup I think so...

Correct Jesuriya

England's highest finish in the World Cup following their 1966 triumph was when they finished in 4th place at the 1990 World Cup in Italy. They lost to Italy in the third place match 2-1, Italy's goals were scored by Baggio and Schillaci, while England's goal was scored by Platt

Ouch, how did I forget that. The semis against the Germans was epic

Epic it was to say the least, hopefully the English can step it up for the Euro's and we may get to see a repeat of Germany vs England in a meaningful match

Nottingham forest and ajax maybe?

Pretty sure its Forest and can't think of another one

Oh I got it Porto and Nottingham Forest

Yea Nottingham Forest and Porto have both done it I think

FutureMUplayer right on the mark! Nottingham Forest (1979 and 1980) and Porto (1987 and 2004 with the Special One)

Valencia and Stade de Reims

Right again.... Stade de Reims (1956, 1959; currently play in Ligue 2) and Valencia (2000, 2001)

Hard to believe that Stade de Reims used to be such a good club and now where they are? Same happened to Leeds and Forest sadly
