Me too, and it wasn't really announced, other than Barkely being added just after Mings got injured. I've checked the squad and whilst it doesn't show the swap, the list reflects what I'm saying,
AI said this.
Ross Barkley replaced Tyrone Mings in the Aston Villa UEFA Europa League squad due to Mings' hamstring injury, which is expected to sideline him for several months.
Aston Villa was permitted to make one change to their List A squad for the Europa League group stage, provided the player being replaced was injured for at least 60 days. Mings' injury, sustained against Liverpool on November 1, 2025, met this condition.
This change allowed Barkley, who was not initially registered in the European squad, to be included on the bench for a match against Maccabi Tel Aviv in November 2025.
