Arsenal’s only signing of the summer so far, Yaya Sanogo, could miss the start of the season due to a hamstring injury.

The former Auxerre man was due to report for French U21 duty this week but withdrew from the squad and didn’t make the trip to Finland last weekend for the game against Man City.

If he does miss out, it’s an inauspicious start to his Arsenal career for a player whose career thus far has been plagued by injury.

Arsene Wenger also has doubts over Aaron Ramsey after the Welshman officially withdrew from the Wales squad yesterday.

He suffered an ankle injury against Man City and will be assessed before the weekend.

Meanwhile, England coach, Roy Hodgson, said he’ll take care of Jack Wilshere as the midfielder returns to tentative international duty.

“I have not had the benefit of Jack Wilshere for a qualifying match or an important match,” he said, “so we are pleased to have him back.

“We are aware of the fact that Arsene is careful with him at Arsenal and I will be careful with him as well.”
