Granit Xhaka has been pictured in an Arsenal kit after leaked pictures emerged on Twitter on Saturday morning.

As reported by Football Insider, the Swiss international flew into London on Friday to complete his transfer from Borussia Mochengladbach.

He has undergone at medical at the Gunners’ headquarters and has been pictured posing for what appear to be the club’s official photographers ahead of his unveiling as the club’s first signing of the summer.

Xhaka was pictured with his family outside the main building of the club’s London Colney headquarters and was also pictured in full kit inside the club’s base.

Sources close to the situation have told Football Insider that Xhaka has agreed the terms of a five-year contract worth £120,000-a-week.

As revealed by Football Insider on Tuesday of last week, Arsenal will also pay around £34million for the Swiss sensation in a deal that will be worth £65million in transfer fee and wages.

Xhaka, 23, is also in line to become the second-most expensive signing in the club’s history behind Mesut Ozil, who joined from Real Madrid in 2013 for £34million rising to £40million with add-ons.

The Swiss international has made it clear he is likely to leave Borussia this summer and appeared to say goodbye to fans, fellow players and coaches during his final Bundesliga game last weekend.

Tellingly, the Swiss sensation embraced his manager when he was substituted after 83 minutes into Saturday’s match against Darmstadt 98 and then stayed on for 15 minutes after the match hugging staff and clapping the fans.

He also gave a big hint he was on his way by liking an image on Instagram of an Arsenal fan in a Xhaka 34 shirt with the caption: “Welcome my bro”.

The Bundesliga club revealed on their official website on Tuesday afternoon they have received an offer for the central midfielder.

However, sporting director Max Eberl said Borussia had failed to reach an agreement with the potential buyer.

The German club did not disclose the identity of the club who made the bid but sources have told Football Insider it was submitted by Arsenal.

Arsenal are now confident of completing the signing of the Swiss sensation as they target a proven player who can dominate in the middle of the park.

The Gunners signed Mohamed Elneny from Basel in January and are now keen on another former player of the Swiss club.

Basel academy graduate Xhaka moved to Borussia Mochengladbach in 2012 for £6.75million and has developed into one of the Bundesliga’s outstanding midfielders.

In other Arsenal transfer news, the Gunners are expected to field a £25million offer for one of their star names.
