"Obviously as a player when you join a new club it takes a while and when a new manager comes in it takes time.
"We've got a good squad, a strong squad, and I think we'll be fine.
"It's only normal that a new manager comes in with new ideas and a new formation.
"We're playing a different style this year. It's going to take time but when we adapt it will be fine."
The former West Ham striker ended speculation linking him with a move away White Hart Lane in the transfer window by agreeing a new three-year deal.

"I feel a lot more settled and I'm just getting on with playing well for my club.
"When you know you've actually signed a contract then you can focus and get down to work.
"It feels like it's a new start for everyone and when you do get a start you have to impress the manager to stay in the team."
