Super Eagles star Alex Iwobi came off the bench in the 77th minute as Arsenal deflated wasteful Manchester United 2-0 at the Emirates Stadium to inflict a first English Premier League defeat on Ole Gunnar Solskjaer since he replaced Jose Mourinho in December.
Iwobi, 22, has accumulated a total of 27 league appearances for the Gunners this season.
He failed to add to his three-goal tally in the match that the visitors missed easy opportunities.
The Gunners picked up the victory through a first-half strike from Granit Xhaka, which David de Gea should have kept out, and a second-half penalty from Pierre-Emerick Aubameyang.
Romelu Lukaku wasted a couple of big chances for United either side of Xhaka’s goal as United, unbeaten in 12 top-flight matches before today, slipped below their opponents into fifth place.
Arsenal’s top-four destiny is not quite in their own hands, though, as Chelsea – held to a 1-1 draw by Wolverhampton Wanderers earlier today – can draw level on points if they win their game in hand against Brighton & Hove Albion.
With the result, Arsenal are within a point of bitter rivals Tottenham Hotspur thanks to a third home league win in four meetings with the Red Devils.
