The Gunners suffered a disappointing 3-1 loss to Aston Villa in Saturday's Premier League kick-off, which drew fresh and furious criticism for manager Arsene Wenger as a group of disgruntled fans wrote an open letter to chief executive Ivan Gazidis.

"So frustrated after a good start," he posted on his Instagram account. "Too many things [went] against us yesterday.
"However I trust in our qualities and [we] want to keep our heads up for Wednesday. We need you!"
Lukas Podolski echoed his fellow striker's rallying call on Twitter and also asked the fans to put the miserable opening day defeat behind them.
He said: "Yesterday it was a sad afternoon for AFC. Nevertheless, we need to think positive and win on Wednesday, forget Saturday’s poor performance."
Fenerbahce entertain the Gunners at 19.45BST in three days' time before the two sides meet once more at the Emirates Stadium the following Tuesday.
