Speaking on talkSPORT, Agbonlahor said: "No, I think he deserves praise for what he's achieved. He's got the club into Champions League. First European trophy since 1984, So he deserves a lot of praise. But Spurs have to go now. They have to invest. They have to get rid of the players that aren't good enough. They have to go through it now.
"Can they go next year like Newcastle, Crystal Palace, winning trophies? Can they go again next season and win another trophy, an FA Cup, a Carabao Cup? Can these players get used to winning trophies? Can they go out and get a Champions League squad assembled for next season and have a good go? Why not? You're in it now. This season's forgotten.
"If you need to change the manager, bring in a different manager who's going to get you the right players and you're going to trust with the funds. But Spurs need to stay on top now. You've won the Europa League. You're in the Champions League. Why not go and have a good go?"
