Arsenal captain Thomas Vermaelen says they must be careful to watch Norwich City striker Ricky van Wolfswinkel.
Former Ajax defender Vermaelen knows all about the striker's qualities and says keeping him quiet will be vital for Arsène Wenger's side.
"Norwich have some good players, including Ricky Van Wolfswinkel, who I know very well from my time in Holland," he told the official Arsenal matchday programme.
"I played against him when he first came through into the first team at Vitesse and he then went to Utrecht and abroad to Portugal and [always] scored a lot of goals.
"He is a clinical goalscorer, he makes good runs and is someone that we will definitely need to watch closely."
