Team News: Koscielny faces test ahead of Watford

Arsene Wenger has revealed that Laurent Koscielny has a slight chance to be in the squad for Saturday's late kick off at Watford. The Frenchman, who suffered a hamstring injury in the 2-3 debacle against Olympiakos, has a test tomorrow. Should he not be in the squad, it seems reasonable that he will return against Bayern Munich the following Tuesday.

Of most importance, Alexis Sanchez texted the manager that he was ok, following Chile's 4-3 win against Peru. The validity of Alexis' text remains to be seen, as one would imagine Alexis would say he's "good to go" even if he had his left leg in a cast.

Of less importance, occasional last-minute panic sub Joel Campbell and David Ospina, who's kept around for comedic value, are also apparently okay. Wenger is reported to have forgotten Campbell's phone number.

Mikel Arteta and Mathieu Flamini have both returned to full training, and could also make the squad.
