Arsenal boss Arsene Wenger is refusing to set a date for the return of Jack Wilshere, but says the 20-year-old is progressing towards full fitness.
The England international hasn't made a competitive appearance since England's draw with Switzerland last June, after picking up an ankle problem in a pre-season friendly against the New York Red Bulls.
Having yet to feature for Arsenal this season, plenty are questioning whether the midfielder will come back in time to contribute to the club's top four challenge, or England's Euro 2012 campaign.
"It is difficult to set a deadline on Jack," Wenger said. "We go week by week with him. But his last scan was very good so we don't have worry anymore.
"It is about progress and fitness, however I can't set a date."
The French boss had further good news concerning another of his injury stricken middle-men, Abou Diaby, who lasted just 29 minutes in his comeback against Liverpool earlier this month before picking up a hamstring injury.
Elsewhere, Thomas Vermaelen is in line to face Everton on Wednesday, while Andre Santos is fit as he looks to make his first appearance since December.
"Vermaelen had a kick on his calf and after the game he had a big pain but he is alright," he added. "Diaby is back but he is with the reserves at Liverpool. He will play for an hour.
"He is fit enough to start but he was like that for the Newcastle game."
The Gunners will look to crank the pressure up on third place Tottenham Hotspur, with victory at Goodison Park, as their rivals host Stoke City.
