The Argentine, a powerful influence at the back ever since being brought into the team last November, damaged his knee ligaments during a 2-1 win over Anderlecht in April.
He underwent surgery immediately and was given a rough return date of January 2018 – the standard nine month spell for ACL injuries.
But Mourinho has confirmed that Rojo could return in time to aid Man United in the typically hectic December period.
“Marcos no chance before December as an example, so our squad is not so big,” he said.
There is something fitting about the way Rojo, a man who has always struggled to fully impose himself on the club, suffered a major injury just when he was starting to look irreplaceable.
We have to remember that football has no favourites, no safe zones, and harbours the omnipotent capacity to send particular narratives and entire careers into the bin with one swing of the pendulum.
How Rojo will recover from such a lengthy spell remains to be seen, but if he can pick up from where he left off upon his return it will, no doubt, feel like a new signing.
