Vincent Janssen is fighting for his future at Tottenham.
The £17million flop has seen his first-team chances drift away in recent weeks.
He said: “I have given myself 12 months to succeed in the Premier League with Tottenham. And those 12 months are not over yet. The level is really high here. Up until last week we were second in the league.
“Don't forget I had only played one season at the highest level in Holland when Spurs bought me from AZ Alkmaar. In a short period of time I have made some big steps forward in my career.
“I'm not going to throw the towel in just because things are not going great for the first time in my career. I am jumping to put the Spurs shirt on, but I will have to prove to the coach that I deserve to play."
