Bellerin had a scan on Tuesday that showed no ligament damage and underwent further tests on Wednesday, with the manager saying that "it doesn't look a long-term problem".
As a man who spent over eight years on Arsenal's books as a player, Henry is reluctant to be drawn on whether Wenger - a man he enjoyed so much success under - should be removed from a contract which is due to run until 2019.
"I think that victory through harmony can take a lot of different meanings, but for me victory through harmony comes from communication".
"At the moment it's certainly hard when you go through a patch like that".
Bellerin "wants to leave Arsenal", but Sport say he's well aware of the difficulties involved in a transfer, given how inflated the current market is. But the atmosphere in our team has to be good and it is good as well, because we can not bury our heads in the sand right now. Milan cruised past Bulgarian champions Ludogorets with a 4-0 aggregate win in the round of 32, while Arsenal ran out eventual 4-2 aggregate winners over Swedish side Ostersund. Maybe we are at a time change is coming and surely the board and owner must realise that.
He added that Arsenal's recent struggles had been "difficult for the team" but called on the squad to stay united.
Defeat to Milan over two legs could see the most hard of situations presented to Wenger, who has also now conceded he had to be "realistic" of the importance the Europa League now holds.
"We need to be together".
Worse was to come for Arsenal in the 26th minute when Laurent Koscielny gave the ball away before Shkodran Mustafi could not reach Gross's pinpoint cross, allowing Murray a free header that the striker directed past Cech for his 11th league goal of the season.
