Arsenal fear Bukayo Saka could miss a minimum of six weeks with the quadriceps injury he sustained in their Champions League tie against Bayern Munich.

The 25-year-old will undergo an MRI scan on Friday afternoon to better assess the problem, which forced him off in Wednesday's 2-2 draw at the Allianz Arena.

Fluid around the affected muscle has made diagnosing the injury difficult, but club medics are estimating, after early examinations, Saka will miss a minimum of six weeks and it could be even longer.

If those early concerns are realised, he will miss a clutch of key games for the Gunners, as well as England's forthcoming Uefa Nations League matches against Croatia and Spain.

"We need a few more scans and opinions from the specialists," said Arsenal head coach Mikel Arteta.

"When a player has to walk off the pitch, he is struggling to walk without any pain, and is restricted to movement; it is not a good sign. Let's be a little bit patient so we can give a definitive assessment.

"He's got another MRI."
