Arsenal are close to completing the signing of Borussia Monchengladbach captain Granit Xhaka.

The clubs have reached an agreement on a deal reported to be worth £30m for the Switzerland central midfielder.

Xhaka, 23, has flown to London to finalise personal terms and have a medical, scheduled for this weekend.

His arrival will strengthen a midfield depleted by the departures of Mikel Arteta, Tomas Rosicky and - possibly - Mathieu Flamini.

Xhaka will become Arsenal's first acquisition in what is expected to be a busy transfer window at the Emirates Stadium.
