The pair started the clash against the London club where Ole Gunnar Solskjaer’s men were arguably lucky to have won.
United scraped by 2-1 victors despite playing poorly all match and supporters were not pleased with some of the players.
Mata and Rojo were the main targets with the former’s contract set to expire this summer.
The Argentine has hardly had a sniff of first-team action this season but supporters aren’t too fussed about that.
Marcos Rojo looked extremely out of touch today. He was mentally too slow. Muscle memory is an incredible thing and players need to play consistently in order to develop it. https://t.co/EDtPYBrxVQ

Marcos Rojo please leave my club. #mufc

Rojo is a crap left back. May as well be back in Argentina burning his toast because his positional sense is shit

With all due respect to Mata, he is past it for Man Utd. Rarely gets a grip of games he is played in nowadays. Think it's time to politely move on.

We have started very poorly and Juan Mata is a Championship player at most. He has declined unbelievably since joining Manchester United. #mufc

Mata was diabolical again, strange why Ole persists with him over Pereira still as well. Fred meanwhile looking superb again is a major positive. #mufc

Many fans believe Juan has declined heavily since coming to Old Trafford from Chelsea during David Moyes’ reign.
The Spaniard has often been played out of position but to be fair to Solskjaer, he’s slotted the player into the natural attacking-midfield role.
It’s where Mata started vs West Ham and it’s safe to say he was disappointing though Marcos wasn’t pleasing either.
The former Sporting man has often struggled at left-back and he was poor on Saturday afternoon as well though he could somewhat be excused for returning from injury.
Ole may be tempted to allow Juan’s contract to run out and move Rojo on this summer as he attempts a squad overhaul.
