Arsenal defender Per Mertesacker has hailed the impact this season of Alexis Sanchez.
Alexis scored his 14th goal for the Gunners against Southampton on Wednesday - the eighth time he has broken the deadlock this season.
"He's unpredictable and even if he loses the ball, he¹s so quick in transition and that is absolutely amazing," Mertesacker told Arsenal Player. "Every day he's in and has so much energy.
"He'll never give up and that's the South American or Chilean mentality he brings to the squad. He scores vital winners for us and that keeps our confidence - and the confidence he can deliver every single game - high.
"That causes threats for any team in the world and I'm very pleased with his performances and pleased to have him here.
"We are enjoying ourselves a bit more after these three wins and defensively we have been very solid. [1-0 wins] are the best way for us to be successful at the moment."
