It is only six weeks since we last hosted Manchester United at Emirates Stadium - but Unai Emery expects his side to deliver a very different performance this time around.
That previous encounter was in the Emirates FA Cup, when two first-half goals proved to be costly as we were knocked out by Ole Gunnar Solksjaer's side.
So what does our head coach expect from this clash?
"[There can be] similarities on Sunday because they have similar players, because they are in a good moment like they were then, but we played well, we created chances," he said.
"We played against a big team and at some moments showed we can fight and battle with them, but we lost and that is the reality. We need on Sunday to do some different tactical and individual work and after find better efficiency against them.
"We need fresh players, players with energy, we need quality, we need good combinations, and we need the players who start on the bench after they can help us on the pitch and deliver a big performance as well.
"It is not a definitive [match]. We are in a way of being consistent, we have 38 matches and Sunday is against Manchester United against a team who also battle for 38 matches and it is important to do it in this moment because this three points are for us or for them.
"I don't think it is definitive, but we need to show and push on Sunday to take more possibility to finish in the top four."
