Arteta concerned about setback for Calafiori, says Arsenal boss

It has now been revealed that Calafiori has sustained a knee strain.

Arteta remarked afterwards: "Ben, it was my decision to take him out. He had a yellow care and we’ve played enough with 10 men in recent periods. They had a lot of density on that side, a lot of players on that side, so I didn’t want to take any chances there.

"With Riccy he had to come off because he felt something. I don’t know the extent of it so in that sense not great news."
