Arsenal boss Arsene Wenger has been given cause for concern following his side's master-class 2-0 victory over Hull City last night, after it emerged today that midfield star Mathieu Flamini picked up a groin injury.
According to Goal the Frenchman, who has underpinned a large portion of the success the Gunners have enjoyed so far this term, is due to undergo scans today to assess the extent of the issue at hand.
Wenger made the decision to rest a number of regular first-team stars in the match against Hull, with the likes of Olivier Giroud, Jack Wilshere, Mikel Arteta and Theo Walcott all taking their places on the bench.
However the Frenchman was believed to be wary of weakening his side too much and so Mesut Ozil, Aaron Ramsey and Flamini all started.
Arsenal will no doubt be cursing their luck at the news of the injury, particularly since their dominance ensured that the victory over Steve Bruce's side was relatively comfortable.
The blow is likely to be made even harder to swallow given the fact that Flamini has established himself as key player during this season's drive towards the title.
