The Gunners will welcome the Red Devils to north London knowing that a victory would see Arsenal leapfrog their bitter rivals into fourth spot in the table.
Emery’s side were held to a 2-2 draw with Manchester United at Old Trafford back in December in a game that the Gunners should have won but paid the price for defensive lapses.
Ole Gunnar Solskjaer has since taken over the reins of the 20-time English champions and the Norwegian masterminded Manchester United’s 3-1 win over Arsenal in the FA Cup fifth round in January.

Manchester United will travel to the English capital full of confidence after overturning a 2-0 deficit to beat Paris Saint-Germain 3-1 at Parc des Princes in midweek.

Emery, who replaced Arsene Wenger at The Emirates last summer, dropped a hint that he may try something different tactically against Manchester United.
“Our last matches in the Premier League we have big confidence and at home we are playing with big consistency,” Emery told Sky Sports. “Sunday against Manchester United is a very tough match.
“They are in their best moment of the season but we play with our supporters at home and we want to create a big atmosphere to help us find our best performance.
“We want to carry on our mentality. This big opportunity is because we are keeping consistency in the Premier League. When we had some difficult moments in matches we can find good performances and we are very close to Manchester United in the table.”
Emery added: “We played very well, created chances, we played with some moments showing we can fight and battle them, but we lost.
“They are like they were, in a good moment. On Sunday we need to do something different tactically and individually and find better efficiency against them.”
Arsenal are looking to finish in the top four for the first time since 2015-16.
