It remains to be seen how much longer Wenger will remain at the Emirates Stadium helm, as talk of a new contract is yet to see pen put to paper.

"The boss has been around for so long, had so much experience, I'm sure he's been through times much worse.
"We believe in him, he believes in us and I'm sure he'll work for a long time."
