Manchester United faced a disappointing performance against Leeds, struggling after a 24-day gap since their last match. The game ended with boos for manager Michael Carrick as the team dealt with the fallout from a controversial red card for Martinez.
It had been often mentioned in the build-up that Manchester United had a 24-day gap in games since their 2-2 draw at Bournemouth.
That might have been a legitimate explanation for their sluggishness in an opening period when they were totally outplayed by a Leeds side that had been sharpened by their FA Cup win at West Ham eight days earlier.
It resulted in Carrick striding to the dressing room with the sound of boos ringing in his ears as the home fans made clear their thoughts of what they had just witnessed.
They did improve in the second half but the result is almost secondary to the consequences of Martinez's ridiculous red card.

Every one of those fixtures represents a serious threat to Manchester United's Champions League hopes.
But the Chelsea trip may have an added issue. Maguire should find out in the next 48 hours whether the Football Association (FA) charge into his reaction to being sent off at Bournemouth last month means he is suspended for another game.
If it does, the likelihood is 19-year-old Ayden Heaven will be partnering 20-year-old Yoro in central defence.
Carrick has cruised through his first few months at the helm. Now the problems are mounting up.
Manchester United's sluggishness was attributed to a 24-day gap between games, which left them outplayed in the first half.
Martinez's red card had significant implications for the team's performance and strategy, overshadowing the match result.
