It must have hurt Colombian striker Radamel Falcao when he was taken off against League One outfit Preston North End in the FA Cup on Monday night, but Louis van Gaal's decision to keep him on the bench today must have hurt him even more.
There's no doubt about it, as Swansea City took the lead against Manchester United at the Liberty Stadium this afternoon, Falcao would have been expecting a shout from his manager.
The final blow
That, despite Van Gaal having one final substitute up his sleeve, did not happen. Instead, as United attempted to save the game, Spanish playmaker Juan Mata was sent on, and United failed to break the Swans down as they suffered their fifth league defeat of the campaign.
Ok, we all know that Falcao has struggled to settle in England, but surely Van Gaal should have turned to his No.9 when United needed him most.
Struggles of others
After all, from the sidelines, the forward had to watch the likes of Robin van Persie and Marouane Fellaini put in dismal performances in the final third of the pitch.
Dutchman Van Persie, who has also been off the pace throughout the course of the season, was non existent at times, and offered very little despite leading the line.
Fellaini, meanwhile, had a day to forget as he produced foul after foul and failed to take the game to the Welsh outfit. Wayne Rooney, who moved into the front-line, offered more, but even he wasn't at his sublime best.
Manchester United needed another striker on the pitch. James Wilson wasn't on the bench, so why didn't Van Gaal turn to Falcao? It's a bizarre decision and one that he will probably now be regretting.
It's probably over
For Falcao, though, he must know his time is up at the Theatre of Dreams. In fact, Van Gaal has pretty much ended the player's Manchester United career. Is there any turning back now? What's the point?
Imagine if Manchester United actually paid up for the Monaco forward. If reports are to be believed, Falcao will only become a Red Devil on a permanent basis as long as they pay a monster £44 million fee.
Unfortunately for the forward, four goals in 19 appearances just isn't good enough, and Van Gaal has clearly seen enough.
The only real surprise is that Van Gaal opted for Falcao on the bench instead of James Wilson. Expect that to change over the coming weeks as the Colombian's United career continues to fizzle out.
