Barcelona midfield ace Andres Iniesta believes he's in the best form of his career.

Barca are keen to tie Iniesta to a new contract given his sparkling performances so far this season and the young midfielder declared: "Perhaps it is the best moment of my career, but it is the result of hard work.

"Hopefully I can maintain this level for a long time and things continue going well for me, because it makes me very happy."
