Arsène Wenger believes there is still much to come from the "exceptional talent" that is Cesc Fabregas.
The midfielder has already notched up 12 goals this season and is set to return to the Arsenal side for Sunday's trip to Bolton following a hamstring injury.
The Spanish international came off the bench to score a match-changing brace in his last game, the 3-0 victory over Aston Villa, but Wenger says the Gunners' inspirational captain is never content and still strives to improve his all-round game.
"Cesc is a player who is an exceptional talent," said the manager. "But part of the exceptional talent is that he is never happy with what he is delivering.
"There is a lot more to come from him, because these players always get better.
"When he does something you feel straightway he analyses 'ah, I did that wrong' and the next time the right answer comes.
"That is how the big players improve, that means there is a lot to come from him.
"Today he is stronger defensively than three years ago. He is stronger in his runs, he is stronger in his long passing and his left-foot is better.
"But he can still be better in the air. He can score goals in the air because once you get into the box at the right moment you can score as well with headers. With his left foot and his heading, there is a lot more to come from him. "Copyright 2015 The Arsenal Football Club plc.
