"The club were ruthless in the end. Just minutes after being sacked they were in there," a source told the Sun.
"It took just 15 minutes to consign Jose to history. They dumped all his stuff into a white transit van. He spoke briefly to some of the support staff but spent most of his time in office on the day."
In another stunning revelation, the Sunday Times claimed a senior United player played a key part in Mourinho's shock departure.
The unnamed player - a regular contributor during Mourinho's tenure - phoned Woodward after the Liverpool loss, demanding the manager's sacking, the paper reported.
This led to late night phone calls to the United owners, the Glaziers in America, ultimately sealing Mourinho's fate.
The Times also claimed several members of the United squad celebrated after Mourinho's departure.
Former United hero Ole Gunnar Solskjaer has taken over from Mourinho as interim manager with Tottenham Hotspur boss Mauricio Pochettino the big favourite as full-time successor.
