Arsenal have received an injury boost ahead of this weekend's Premier League trip to Watford.

Four players are back in contention following layoffs, including Mesut Ozil and Danny Welbeck, according to Football.London.

Meanwhile, Laurent Koscielny and Sead Kolasinac face late fitness tests and Francis Coquelin is expected to return to the squad after recovering from a hamstring problem.

The news will come as a welcome boost for Gunners boss Arsene Wenger, who lost Shkodran Mustafi to a hamstring injury during the international break.

However, the Frenchman faces a selection problem in the final third now that all of his attacking options are at his disposal.
