Arsenal will be without both Kieran Tierney and David Luiz for the crucial Europa League quarter-final clash against Slavia Prague on Thursday, according to reports.

Tierney limped off with a knee injury in the closing stages of the first half during the 3-0 defeat to Liverpool at the weekend. There are fears it could be a serious problem and the Scottish international is not expected to be involved in either leg of the European tie.

A scan in the next 48 hours is expected to determine how long Tierney will be out for, with an initial expectation that he will be out for at least a few weeks.

The news about Tierney follows on from confirmation that David Luiz underwent minor surgery on his own knee injury. The Gunners have said that the defender is expected to return in “weeks” but whether he’ll be back before the end of the season, it remains to be seen.

Manager Mikel Arteta is also sweating over the fitness of Emile Smith Rowe (hip), Bukayo Saka (hamstring) and Granit Xhaka (illness) ahead of the game later this week.
