It is far from ideal for the Gunners.
Mikel Merino is set for a lengthy period on the sidelines as a potential return date has been set.
After signing from Real Sociedad this summer, Merino was a marquee signing under Mikel Arteta as they looked to bolster their squad ahead of a title charge.
Impressing in the Euro 2024 tournament as Spain were victorious, Merino bagged a priceless last minute header against Germany in the quarter-final.
Earning mass plaudits during the festival of football, Arteta then swooped in late for his man.
Now however, he is set for a prolonged period on the sidelines.
As per Mail Sport, Merino is set to miss close to two months with a fractured shoulder suffered in his first Arsenal training session.
There is hope Merino will have a chance to return after the October international break.
