The Gunners raced into a 3-0 first-half lead as they thrashed Louis van Gaal’s men in the Premier League at The Emirates back in October.
Arsenal head to Old Trafford on Sunday looking to return to winning ways after the disappointment of their 2-0 loss to Barcelona in the Champions League on Tuesday night.
And Arsenal defender Mertesacker has outlined the kind of performance the Gunners will need to produce at Old Trafford if they are to get their title bid back on track on Sunday.
Speaking to Arsenal Player, Mertesacker said: “[In October] I think we came out really strong, trusted in ourselves, nicked balls from them in their final third and then broke them down. It was remarkable how we played and how we reacted.
“We were really active from the start, pressed them high and tried to get the ball as quickly as possible. It completely worked out. It will be a different game this time but I want to see the same effort from our side.
“That was our plan, to get the ball early, so the distance between where we got the ball and the goal was short. We are dangerous when we win the ball early. I think that’s something we need to emphasise.
“I would say we are more comfortable going there, or away from home in general, and performing well and to our best [than before]. We need a good performance in Manchester, there’s no doubt about it.”
Arsenal are currently five points behind leaders Leicester after the Foxes beat Norwich City 1-0 on Saturday to cement their place at the top of the Premier League table.
