Harry Redknapp is planning a summer of reconstruction at Queens Park Rangers after practically abandoning hope of rescuing the club from relegation to the Championship this season.

In theory QPR could still survive if they win all four of their remaining games but that is extremely unlikely and their demotion will be confirmed even if they beat Reading on Sunday, with a victory for Aston Villa against Sunderland on Monday condemning Redknapp's side to a fate that has long looked inevitable.

Redknapp, however, says neither he nor the club's owners will walk away from Loftus Road and will meet next week to figure out how to bounce back. "They're not going to roll over and die," Redknapp said of the owners. "They're determined people and they want to come back again next year. They've had a blip this year but hopefully we can put it right next year. Next year could be a great year."

Redknapp rubbished suggestions that, at 66, he would no longer have the appetite for the slog of a promotion campaign from the Championship. "Of course I've got the heart for it," he said. "It's a big challenge but this is a good club. It will be very hard to come straight back but that's the aim. We've got the summer so there'll be no excuses. We've got to get the right players to go with the ones we've got."

There is sure to be a high turnover of players, with Redknapp eager to retain certain key personnel while trying to cut loose ones who are unneeded but tied into lucrative contracts. "The silly thing about this game is that quite often the ones you want to keep are the ones who want to go and the ones you'd like to let go don't want to go. At the end of the day they've all got contracts, so I'm sure we'll keep the ones we want to keep and we'll see how we go with the others."

One player whom Redknapp says the club may hang on to is Joey Barton, who is scheduled to return from his loan stint at Marseille. Barton has made it clear he wishes to stay in France but Redknapp says the midfielder will play in the Championship next season unless Marseille and QPR agree a transfer. "He's done well at Marseille and he's got a nice lifestyle there but he belongs to us so, if we can't do a deal with Marseille, he'll be welcome back here and I'm sure he'd be a big asset to us. But it will be difficult to get him back. I saw where he lives when I went to watch [Loïc] Rémy play and I don't know if you'd want to leave that."

Rémy, the January signing who is QPR's top scorer this season with five goals from 10 matches, also remains under contract but Redknapp knows the France international is likely to leave. "We'd obviously like to keep him but it's going to be difficult. He could score 20 goals in a full season in the Premier League. We'll have to sit down with him and see what his plans are."

Redknapp says that the size of QPR's squad and the amount of negotiation to be done to keep, buy and sell players means this summer's job will be even more complicated than the one he did before leading Portsmouth to promotion in 2003. "This will be tougher because I haven't got a blank sheet to start with. I've got a lot of players here so that's going to be the hard part. It's going to be a juggling act."

He said he is particularly keen to attract players "with good character", sprucing up the squad with ambitious youngsters and inspirational seasoned campaigners who could prove as influential as Teddy Sheringham, Paul Merson and Arjan de Zeeuw were at Portsmouth. "There are still bargains out there; you don't have to spend fortunes," said Redknapp.

QPR obtained planning permission for a new training ground this week and Redknapp has also ordered a new, smoother pitch to be laid at Loftus Road. "I want to produce a team that plays good football, so you need a good surface. It's absolutely wrong to say you can't play your way out of the Championship."
