Manchester United should have appointed Roberto Martinez - not David Moyes - as Sir Alex Ferguson's successor, according to Wigan Athletic chairman Dave Whelan, reports Sky Sports.
The Spaniard ended his four-year spell at the DW Stadium when he was allowed to take over from Moyes at Goodison Park, following the Latics' relegation from the Premier League last season.
Whelan has heralded Martinez as "one of the greatest managers in the world", and said that Manchester United missed a trick not considering the 40-year-old for the job at Old Trafford, in the aftermath of Ferguson's retirement announcement.
"I think he's the best manager in the world and I was a little surprised that Man U didn't come for him because I knew that Alex was going to retire," the 77-year-old told Sky Sports News.
"Alex had already told me that he was thinking of retiring and I was a bit surprised that Man U didn't.
"They have still got a great lad in David Moyes, let me say that, he's still a great manager, but Roberto now going to Everton, he will take Everton to places they can only dream about."
After a modest start to life at Manchester United, Moyes is already facing an uphill battle to retain the Premier League title this season, with the champions currently sixth in the table, seven points behind leaders Arsenal.
However, after a convincing 5-0 victory over Bayer Leverkusen in the Champions League last night, the Red Devils are expected to kick-on in an attempt to close the gap in the month ahead.
