Steffen Freund admits Emmanuel Adebayor is unhappy, but the Tottenham assistant manager believes the striker still has a key part to play for the club this season.
Adebayor was a big hit on loan from Manchester City last season, but after signing a permanent deal at White Hart Lane in the summer he has failed to break back in to the starting XI this term thanks to the sharp form of Jermain Defoe.
But assistant head coach Freund insists the powerful hitman still has a big role to play for the team this year, and said: "Adebayor is sick. We will have a look (to see if he is fit for Norwich). If you're not playing and you're injured then of course you are not happy. He's really sick but hopefully he will be back in time. He is one of the best strikers in the Premier League."
He went on: "We are happy to have him back here. We need every Tottenham Hotspur player. If Andre wants to rotate or change the position up front, it's good to have every player fit."
Spurs head to Carrow Road in the Capital One Cup on Wednesday after returning to winning ways with a 2-1 win at Southampton, where Gareth Bale was the architect of his former team's downfall.
Bale has challenged his team-mates to build on the momentum gained from Sunday's win by picking up back-to-back victories against Norwich and Wigan.
"We're enjoying our football now and we're on a good run so it is good times but we just need to keep our feet on the ground and move forward," he said.
