Arsenal manager Arsène Wenger as hailed Chelsea forward Diego Costa.
The Brazilian-born Spain international will come against Wenger’s side at Stamford Bridge on Sunday and the Frenchman is well aware of his capabilities.
“He has done fantastically well," he said, as reported by Sky Sports.
“He has all the aspects of a striker that you like – he is focused, always determined and ready for a fight.
“He has also got players who can feed him like [Cesc] Fàbregas and Eden Hazard, who can find him with final balls.
“Costa is a very efficient player. The timing of his runs and his determination, his killing determination – you feel he is a killer, he has that in him [when in front of goal]."
