Arsenal's week took a turn for the worse yesterday after the Chilean FA confirmed that Alexis Sanchez has picked up a muscular tear in his calf, which could leave the Gunners without their star-man for a number of weeks.

Although the full extent of Alexis' injury is yet to be revealed, as Arsenal are forced to await the results of a scan today, fear is rising in North London amidst suggestions Alexis could be out until Christmas.

With Arsenal facing a huge clash with Manchester United in a week-and-a-half, before then tackling Paris Saint-Germain in the Champions League, the Gunners will be concerned that their key-player could miss the most important stage of the season so far.

If Alexis was to remain sidelined, Olivier Giroud would step into a starting spot but with Lucas Perez and Danny Welbeck also injured, it would leave the Gunners with a severe lack of options for the striking berth in their squad.

Naturally, Arsenal fans have been extremely concerned and have taken to social media to share their woes.
