Arsenal manager Arsene Wenger has reassured the fans that Jack Wilshere will only be out of action for a few days.
The midfielder was not involved in last week's 3-1 win against Chivas after suffering a knee injury.
But the Frenchman says he could be involved this week when the Gunners face Viking FK and Manchester City in Scandinavia.
"Jack [Wilshere] has a slight problem with his knee," Wenger is quoted as saying by the Daily Star.
"We think it should not be very long.
"He should come back quickly, maybe next week.
"It's a slight patella problem but I think he should be with us on tour on Thursday."
