Townsend has been dropped from the Spurs squad of late, after an argument with Tottenham’s fitness coach, and his first-team chances have been limited.
The England international has barely featured this campaign, and others have jumped ahead of him in the pecking order at White Hart Lane.
And Crooks said: “His job is to force himself with his performances and his form into the set-up.
“You can’t blame Pochettino for picking the players he has until now, as they’ve been on top of their game.
“Andros is a talented player, of course he’ll be irritated not to be in the side, but if he works hard and his attitude is right, he does have a future at the club.”
Townsend has not managed to fit into Mauricio Pochettino’s style at Spurs yet, and he seems to be playing for his future now.
The wide-man has struggled to make an impact under the Argentine’s guidance, and with the January transfer window on the horizon, time could be running out.
Townsend is already behind the likes of Nacer Chadli, Heung-Min Son and Erik Lamela at Spurs, and with Alex Pritchard coming close to a return – his starting opportunities could become even more limited.
Townsend has made seven appearances for Spurs in all competitions so far this season, and he will be hoping to play a part against West Ham United later this afternoon.
