It was a great match. Aston Villa played incredibly. But Arsenal players were very much disappointed with their performance. After the match, Arsenal Boss Mikel Arteta said, "The way we lost today really hurts".
Arteta needs to fix the inconsistency in his team if they are to improve and maybe challenge for the epl title in the coming seasons, they can't go from beating united to losing to Aston villa, of course villa have been in great form this season, even scoring 7 against the defending champions Liverpool, but Arsenal need to be consistent as without that a team can't win the premier league, no doubt Arteta is already doing a good job at the Emirates, but clearly there is more work to be done to transform Arsenal into EPL champions.
Unless Zidane is no longer the manager of the team and Bale overall performance dropping with spurs.
Even if Zidane is no longer manager, I don't think Bale can ever play for Real again, imo, he was treated terribly bad by Zidane as that's no way to get a player out of your plans/team; Bale is either going to make it in Spurs or finally move to another team, but definitely not back to Real Madrid.
