Arsenal dealt new injury worry as Mikel Arteta forced into substitution

Mikel Arteta revealed Ezri Konsa had "some issues" that forced him to come off in Arsenal 's win over Slavia Prague. The Gunners won 2-1 to move up to third in the league-phase standings of the Champions League , despite a sloppy second-half display in which they let their hosts back into the match . Konsa started the match alongside Gabriel, though his place in the side is coming under increasing pressure with William Saliba back in the matchday squad for the first time this season . In the first half, Konsa was seen feeling his knee.
