David Moyes believes the Manchester United board had been conspiring against him for weeks while Sir Alex Ferguson purposely distanced himself before his sacking, reports the Daily Mirror.
Moyes, who was relieved of his position at Old Trafford on Tuesday morning, believes his friend Ferguson was aware board members were preparing to sack him and withdrew his support as a result.
Ferguson hand-picked the then-Everton manager to succeed him after 27-years in charge at Manchester United, but only last 10 months into a six-year contract.
But the Mirror claims that Ferguson's support for Moyes was virtually non-existent in his final days in charge at Old Trafford. Not only were most of the board against him but it is growing increasingly clear that the squad were too.
Moyes also believes that Manchester United officials decided to sack him weeks ago but waited until Champions League qualification was mathematically impossible to achieve.
According to reports, a failure clause in Moyes' contract allowed Manchester United to sack him with only 12-months salary if he failed to finish in the top four of the Premier League.
That limited his compensation to £4.5m where it would have otherwise been over £20m.
Finally, Moyes believes his job was made harder by the fact that chief executive David Gill stood down along with Ferguson, leaving the inexperienced Ed Woodward in charge.
Woodward was new to the transfer market and it told last summer as the pair struggled to secure the marquee signing they tried all summer for.
