But they could be without key defender Laurent Koscielny and midfield duo Mikel Arteta and Mathieu Flamini.

Koscielny limped out of the Champions League defeat to Olympiakos last month with a hamstring injury and hasn't played since.

"Koscielny has a slight chance to be back on Saturday," Wenger said. "He has a definite test tomorrow."

TOUCH-AND-GO: Koscielny is a doubt for Arsenal

DUO DOUBT: Arteta and Flamini have struggled for fitness

On Arteta and Flamini, he added: "[They] are back in full training. We need to see how they are and how confident they are, but we can’t rule it out.

"From the internationals we only have positive news.

CROCKED: Wilshere and Welbeck are still a way off returning

COMEBACK: Rosicky is eyeing a return in January

"We are still waiting for Campbell, Alexis and Ospina to return, but they all texted back to say they are OK, so we just have to see if they were objective in their assessment."

Wenger will definitely be without Jack Wilshere, Tomas Rosicky and Danny Welbeck for the Watford clash.

Wilshere is still recovering from an operation on a broken leg, while Welbeck and Rosicky are targeting returns from knee problems in the New Year.
