Former Arsenal defender Martin Keown has hailed Cesc Fabregas as the complete midfielder.
Keown believes the 20-year-old Spaniard heads back to his homeland for the match at Sevilla as the jewel in the Gunners' crown after rediscovering the goalscoring touch that deserted him last season.
"Cesc is the orchestrator of everything. He's developed into an outstanding player and looks like a natural winner," he said.
"The goals he has been scoring this season are the icing on the cake.
"He was fairly prolific as a kid and it was mystery last season why he struggled to find the back of the net.
"I was told that he needed to calm down in front of goal and he has managed that. He now looks very calm when he has a chance.
"Cesc never allowed himself to get bullied, but sometimes he was a bit naive in the way he played.
"But that's gone now and he's a fighter - he wants to play football and put his foot in.
"He's got everything he needs and now of course he's scoring goals as well.
"He's Arsenal's driving force and looks so hungry and passionate. Coupled with that he plays a great technical game."
