@thirdrailsports: Unai Emery is walking back into Camp Nou — the stadium where his PSG side were humiliated in the Champions League. He never got to go back with Arsenal. Never with Villarreal. Now he's doing it with Aston Villa. Barcelona's defence is already stretched. Their key defender is practically ruled out with an ankle injury. Emery has been building to a moment like this. Camp Nou is it. Emery never returned to Camp Nou with Arsenal or Villarreal. Does Villa finally give him the result he was denied with PSG? #AstонVilla #ChampionsLeague #ThirdRailSports
