Alexis Sanchez won't be winning the Champions League with Manchester United this season - and Arsenal fans seem delighted.

The Red Devils were eliminated in the last-16 stage of the competition by Sevilla following Tuesday night's shock 2-1 win at Old Trafford.

Sanchez, who quit Arsenal for United in a swap deal which saw Henrikh Mkhitaryan move the other way, posted a relatively disappointing performance.

The Chilean has looked nowhere near his best since arriving in Manchester, following a series of lifeless displays.

And Arsenal fans on Twitter are delighted that their former hero is hardly setting the world alight.

Here is some of the best social media reaction.

Sanchez is undoubtedly a world-class talent and few would back against him to start proving fans of the North London club wrong eventually.

But for now the 29-year-old's confidence looks shot to bits and it will likely stay that way until he improves on his one-goal in nine-game ratio for United so far.
