Sead Kolasinac will be out for at least the next two months after picking up a knee injury against Chelsea while Aaron Ramsey is expected back in training next week.

Heading into Arsenal’s final pre-season game of the summer against Lazio on Saturday evening, Arsenal gave an update on the two players who both picked up problems in Dublin midweek.

Ramsey missed out on the game after picking up a calf problem in the warm-up but after the match, Unai Emery said he didn’t think the problem was serious.  He “developed tightness in his right calf. Continues to be assessed. Aiming to train next week,” read the statement on Arsenal.com.

This is Ramsey’s third calf problem in the last 18 months, the first keeping him out for 31 days/five matches at the start of 2017. The second saw him miss just four days and one game.

Kolasinac will be out for a good bit longer. The Bosnian is facing at least two months on the sidelines with knee ligament damage. He “Sustained an injury to his left knee. Will be out for 8-10 weeks,” said Arsenal.com.

The 25-year-old looked like he might have been about to take Nacho Monreal’s starting place in the Arsenal lineup for the new season but the club will now have to rely on the aging Spaniard and hope he doesn’t pick up any problems either.
