Arsenal boss Arsene Wenger says Cesc Fabregas is now the "complete" midfield player.
The Spanish international has already scored nine goals in 17 games this season and recently said he felt "happier than ever" at Arsenal.
Wenger brought Fabregas into the Arsenal side at the age of 16 and is delighted with the way he has developed.
"First of all he is a winner," the Frenchman told arsenal.com. "He is a complete midfielder.
"He has become a complete midfielder because he can defend now, he has kept his vision and I believe he has added some physical power to his game.
"If you compare Fabregas two years ago and today, physically they are completely different.
"He has got that injection of power to his body and that makes him a different player."
