Arsene Wenger will take an Arsenal team to Old Trafford for the final time as Gunners manager after the 68-year-old confirmed that he will stand down at the end of the 2017-18 season.
Arsenal played out a 1-1 draw with 10-man Atletico Madrid in the first leg of their Europa League semi-final on Thursday night after Antoine Griezmann’s late equaliser cancelled out Alexandre Lacazette’s opener.
The Gunners are in sixth place in the Premier League and unlikely to qualify for next season’s Champions League unless Arsenal can win the Europa League trophy to secure a spot in Europe’s premier club competition.
Manchester United are looking to wrap up second place in the Premier League table ahead of Liverpool FC to secure progression in the English top flight in Jose Mourinho’s second season in charge.
Former Arsenal star Merson is backing Manchester United to secure a comfortable win against the Gunners in Wenger’s final trip to Old Trafford in charge of the north London outfit on Sunday.
“Arsenal have got no choice but to rest players at Old Trafford,” Merson told Sky Sports.
“They can’t get in the top four so the Europa League is the priority and their only route into the Champions League next season. I cannot begin to think who will start against United because they have to rest, so it’s a good time to play Arsenal.”
Merson added: “It’s a shame for Arsene Wenger that this game comes in between the Atletico Madrid games, but winning the Europa League would make up for defeat on his last trip to Old Trafford.”
Arsenal signed Pierre-Emerick Aubameyang and Henrikh Mkhitaryan in the January transfer window.
