Manchester United succumbed to a 4-1 defeat against Borussia Dortmund in the first game of their pre-season tour of Asia earlier today and fans were left dismayed at the performance.

Coming in for particular criticism were centre-back duo Phil Jones and Marcos Rojo, with the latter angering the United faithful with a woeful display.

The 26-year old came on for Jones at half-time, with United already two-nil down, and was partially culpable for Dortmund’s next two goals.

He was beaten far too easily by the impressive Ousmane Dembele for the third goal and failed to close down Gonzalo Castro quick enough on the edge of the box as Dortmund made it four.

Rojo will have done little to convince Jose Mourinho of the merit of keeping him around next season and the Red Devils boss may be forced back into the transfer market to bolster his defence.

United have brought in Zlatan Ibrahimovic, Henrikh Mkhitaryan and Eric Bailly so far this summer and were expected to finish their business up with the apparently imminent signing of Paul Pogba – as reported by the Sun – but that may not be the case after today’s alarming performance.

We've compiled the best of the reaction to Rojo's performance below:
