Tonight's game takes place at the Emirates stadium while kick-off is scheduled for 20:05 (GMT).
"We live in a society of 100 per cent security and I thought they would never take a gamble to play this game when I saw the images around the stadium".
Surely everyone knows that last season Arsenal lost the competition in the fight for the first 4 lines in the Premier League table, and the 5th ranked sent the "Gunners" to the group stage of the Europa League.
"Yes, they are known for their very passionate support".
As many as 20,000 Cologne fans are believed to have made the journey from western Germany despite only 3,000 tickets being made available. I don't know, was it mental? "He is still fighting to come back to his best physically, but Sanchez is Sanchez".
The Toffees, who are now 25/1 with Sky Bet to lift the trophy, went into the match having suffered a 3-0 home loss to Tottenham five days earlier and with boss Ronald Koeman stressing they would "need to react" in Italy after that poor performance.
"It is a good opportunity to show we can cope", Wenger said. "But Alexis is Alexis - he's an exceptional player and even if he's not completely back today, physically, he is an exceptional football player and he can deliver a decisive pass or a goal at any moment", the Frenchman said.
"I moved to a four in the second half, [Sead] Kolasinac I think gave us a lot going forward, but as well he pushed Sanchez forward, who played deep in the first half".
We will also see our promising youngsters out there for the Gunners, as no one can get enough of Reiss Nelson, the 17-year-old that could be the needed burst of energy that Arsenal can often sorely need.
