The Gunners midfielder says he knows Xhaka's game well and believes he is a strong addition to the side.
Arsenal midfielder Jack Wilshere has told the club's official website that he knows new signing Granit Xhaka's playing style well and believes he can play the crucial role of holding the club's midfield together this season.
Xhaka became the Gunners first major outfield signing since the summer of 2014 when he joined in deal worth over £30 million from Borussia Monchengladbach at the end of May.
The Swiss international had risen to prominence as a result of some impressive form over the last couple of years for the German side, whom he captained until his exit.
After playing every single minute of Switzerland's Euro 2016 campaign, the 23-year-old linked up with his new teammates for pre-season training under Arsene Wenger.
The man who could become his central midfield partner this term, Wilshere, told the club's official website that he already knows a lot about Xhaka from having watched him and played against him.
The England man believes the new arrival can become a key figure for the Gunners and claimed that he can establish himself as the man who can "hold the midfield together".
Wilshere said: "I've played against him a few times at youth level for England and also for the first team with England, so I know him quite well. I've always thought he was a good player, he's very strong and has got a good left foot.
"He's a leader, he can hold the midfield together and can get things going from back to front. He's a good signing."
Given that Wilshere could also feasibly find himself in direct competition for his place with Xhaka this season depending upon the system Wenger chooses to play, that is high praise indeed.
Xhaka will be keen to make an immediate impact in English football and show that he can successful ride out the transition from the Bundesliga.
