Andre Villas-Boas admitted Tottenham Hotspur would have to improve next season after finishing fifth in the Premier League and is confident he can keep Gareth Bale at his club despite missing out on the Champions League next season.

Bale managed to score the winning goal in Spurs last league game of the season as they ran out 1-0 winners over Sunderland, but despite that victory they finished fifth on the table and outside the Champions League spots for next season.

Spurs finished on 72 points, their highest ever tally in the Premier League which only tells Villas-Boas that his side will improve next season to compete for glory.

“It is a bit disappointing obviously but it did not depend on us and Arsenal did their job to sneak fourth spot,” said the Spurs manager.

“To manage so many points and not make it means the level has come up, and it serves a reference for next season.

“Others have pushed on a level and next year we have to improve, so it is a good lesson to take into next season.

“It is a pity we missed it (Champions League qualification) this season, because normally it would be enough to qualify.”

Speaking on Bale and the suggested rumours he will be leaving the club in the off-season, Villa-Boas feels they will be able to keep their star.

“We have to keep our ambitions high and hold on to the best players,” added AVB.

“The reference is there from the points tally to make it better for the future and to do that we need to hold on to our best assets.

“Today was another great moment of individual brilliance, although the squad in the second half was really, really strong and everyone was pushing for the winner.”
