After a narrow 1-0 victory at home against Rostov, Jose Mourinho hit out at his critics and lamented everything from the Russian pitch in the first leg, to unfavourable scheduling in his eyes.
A lone Juan Mata goal lifted Manchester United into the Europa League quarter-finals, but they'll have to be better if they are to make the competition their best chance at silverware this season.
"We have a lot of enemies," Mourinho said in his post-match comments.
"It is difficult to play on Monday with 10 men, then play on Thursday, and then once again on Sunday at noon.
"People can say we should have played better but the reality is that we have a lot things going against us.
"As a result, Sunday's match against Middlesbrough wasn't approached with much optimism from the Portuguese boss.
"Fatigue pays its price, and we'll probably lose on Sunday," he continued.
"The teams above us don't know anything about being fatigued, about the accumulation of so many matches, about the absence of sleep.
"I'll never forget the UEFA delegate in Rostov telling me that our health insurance would cover our injuries [given concerns over pitch condition]."
