Jose Enrique admits he's yet to win over Liverpool boss Brendan Rodgers.
The Spanish fullback has been played in an attacking role by Rodgers in recent games.
When asked how he felt to hear his place at Liverpool was in jeopardy, Enrique said: "To be honest, you cannot worry about it. I believe in myself. I always have done, no matter what team I have played for. This is the biggest club I have ever played for.
"Every day you have to prove yourself. It doesn't matter how well you have played in the past, it is what you are doing at the minute that counts. If you don't play well, you are on the bench. There are players here waiting to come and take your place. I want to be here for a long time.
"I had some problems with my knee at the start of this season. I had this pain but in the scan, everything was showing okay. Then, one day, the pain had just gone. Now I want to keep improving."
