Tottenham boss Harry Redknapp says they won't improve if they sell their best players.
Redknapp told Sky Sports News: "We just missed out last year, we finished fifth because the four teams in front of us were just a little bit stronger and they are going to get much stronger in the summer.
"So if we don't get stronger then you can't expect to pass them next year, so you don't have to be a rocket scientist to work that one out.
"We need to improve the squad, the team in the summer and get two or three real quality players in.
"If we can do that and keep Luka and Gareth Bale and all them boys we will have a great side again next year."
