Midfielder Xhaka becomes Arsenal's first offseason signing

Arsenal has signed midfielder Granit Xhaka, the team's first addition to the squad in the transfer window.

The 23-year-old Xhaka is joining Arsenal from Borussia Monchengladbach after captaining the German team to fourth place in the Bundesliga.

Arsenal manager Arsene Wenger says "we have been watching him for a long time now and he is a player who will add quality to our squad."

Xhaka will join up with his new Arsenal teammates after playing at the European Championship with Switzerland.

Arsenal, which finished second in the Premier League, has not won the title since 2004.
