Mesut Ozil (Real Madrid to Arsenal, £42.5m)
Forget that a striker, a defensive midfielder, a defender and a goalkeeper were a much higher priority on Arsène Wenger's shopping list, because Arsenal have acquired one of the world's finest playmakers.
There was a reason why Real Madrid fans sang "Don't sell Ozil" at Gareth Bale's unveiling on Monday and Arsenal's collective bar can only be raised by the attacking midfielder's installation in Wenger's first XI.
Quite apart from being a sheer joy to watch, the club's biggest statement signing since Dennis Bergkamp in 1995 can only help those around him – perhaps most notably Jack Wilshere – to hit new heights. The Germany international promises to re-define Wilshere and company's interpretation of the words "invention" and "incision". A record of 94 "assists" for club and country in the past three years tell their own, powerfully persuasive, story.
Ticket prices at the Emirates are eye-wateringly steep but Ozil's arrival guarantees full houses while potentially breathing new life into the Wenger era.
Fabio Borini (Liverpool to Sunderland, loan)
The 22-year-old one-cap Italy striker-cum-wide-attacker scored only twice in 20 appearances for Liverpool following a £10.5m transfer from Roma in 2012 but he did suffer a broken foot and a shoulder injury and had proved prolific in Rome and during a loan stint at Swansea.
Strong, versatile, technically accomplished and hard working, Borini seems well-suited to Paolo Di Canio's winger-propelled 4-4-2 formation and can only benefit from being coached – quite possibly one to one at times – by the Sunderland manager. As a former striker of some ability, who better to unlock Borini's talent?
Do not bet against Borini – one of 14 signings by Sunderland – causing some serious damage to Premier League defences.
Nathan Redmond (Birmingham City to Norwich City, £3.2m)
During a summer in which much of the best transfer business has involved players from overseas, Chris Hughton's acquisition of Redmond, an England Under-21 winger from his former club, Birmingham, stands out.
The 19-year-old, who although primarily right-footed can play on either wing or in the hole, has started extremely well at Carrow Road and could not wish for a better mentor than Hughton.
Indeed, providing he keeps helping create the goals to banish relegation fears, he could be a dark horse to play for England in next summer's World Cup finals in Brazil. (Providing Roy Hodgson's squad qualify).
Erik Pieters (PSV Eindhoven to Stoke City, £3m)
Mark Hughes's plans for Stoke's evolution to much more of a passing side took a sizeable step forward when he signed the Holland left-back from PSV Eindhoven.
The attack-minded Pieters came extremely close to a move to Newcastle United after being spotted by their super scout Graham Carr only to miss out owing to injuries.
Stoke – always inclined to play centre-halves at full-back under Tony Pulis – needed a left-back and the 25-year-old's arrival gives Hughes's team a much better balance.
With a World Cup at the end of it, this is a big season for Pieters and he can help make it a surprisingly good one for Stoke as they aim to start building a little more fluently from the back. A piece of smart business of the shrewd variety that characterised Hughes's time in charge of Blackburn Rovers.
Tom Huddlestone (Tottenham to Hull City, £5.1m)
No player has been capped by England while playing for Hull but Steve Bruce believes Huddlestone can rewrite history. Strong, tall, powerful, with presence and an impressively varied passing range, Huddlestone has the potential to not only add to his four England caps but also keep Hull in the Premier League.
Paolo Di Canio had identified Huddlestone as "the man with the keys" he desperately wanted to control central midfield, but Hull broke the bank to come up with a better offer.
At 26 Huddlestone – an intelligent enough footballer to compensate for his lack of pace – has had his moments of under-achievement but this might be the season when he proves a very big point to not only André Villas-Boas but Roy Hodgson as well.
