The Tottenham manager believes Daniel Levy has to see his money spent more wisely at White Hart Lane.
Tottenham Hotspur have had a good season, but at the end of the campaign they will be empty handed. They lost the Capital One Cup final to Chelsea and it looks as though the Champions League might be out of question.
Mauricio Pochettino is however a very popular head coach at the club with the fans big in support for him.
He also has a fan in a former Tottenham manager, who was also very popular. Harry Redknapp believes that the Argentine has done a good job this season, although he blames the players he has been lumbered with.
"I like the manager, I think he is excellent. He is a great guy as well as well as being a good manager.
"They've not pulled up any trees, let's be honest. Finishing sixth or seventh is not really going forward.
"They bought players in, they haven't spent wisely, the players they have bought in that's not down to him.
"He has been rescued by the kids this year, the Harry Kanes, the [Ryan] Masons, the [Nabil] Bentalebs, Andros Townsend. They have been their best players. For me, they have kept them going, [despite] the signings for me.
"The big signings that came in have been a disaster. That is something Daniel [Levy] is going to have to look at. The recruitment was poor, I think they have changed that around now, have got new people coming in. They need to make more signings that are better than the players they have got."
He certainly has a point when it comes to the signings. The likes of Erik Lamela, Roberto Soldado, Vlad Chiriches, Paulinho and Etienne Capoue all arrived at Spurs at considerable cost with considerable reputations.
But they have flopped, while the likes of Harry Kane have dragged Tottenham toward a positive season.
Spurs will need to do better business in the transfer market this summer if they are to win something next term.
