Former Manchester United coach Rene Meulensteen believes the Red Devils would have won this season’s Premier League title had they appointed Jose Mourinho or Pep Guardiola instead of David Moyes last summer.
Speaking to Voetbal International, the Dutchman said: "Mourinho or Guardiola with this current Man Utd team would finish top, I'm sure."
Meulensteen was offered a reduced role at Old Trafford when Moyes took over from Sir Alex Ferguson last July - but that was rejected by the first-team coach, who left the club along with Mike Phelan and Eric Steele.
Meulensteen believes Moyes’ decision to overhaul the club’s backroom staff played a significant role in his downfall at Old Trafford. The Scot’s tenure was brought to a premature end on Tuesday morning, when he was relieved of his duties after less than a year in the job.
Mourinho was overlooked for the position by Ferguson and other Manchester United officials who decided that Moyes was the right man for the job. However, there have been plenty of rumours over the last 12 months claiming the current Chelsea coach had his heart set on succeeding Ferguson towards the end of his spell at Real Madrid.
Guardiola, meanwhile, had already agreed to become Bayern Munich coach in January 2013 - five months prior to Ferguson announcing his decision to retire.
Manchester United, under Moyes, have suffered their worst campaign of the Premier League era - and interim manager Ryan Giggs now faces an uphill struggle to help the Red Devils qualify for next season’s Europa League.
