Tottenham fullback Kieran Trippier has again admitted his form this season has been disappointing.
His level has dropped this season and, as he admits, he has been at fault for several goals.
"I could have done a lot better than what I have done, I am the first to admit that," he told Sky Sports.
"I look at all the games I play in and review them. I have had chats with the manager and other players too, but it's all about learning and trying to do as best as I can in every game. I always do my best.
"I could have done a lot better since the World Cup."
