Wigan Athletic chairman Dave Whelan believes that Manchester United should have appointed Roberto Martinez as their manager following Sir Alex Ferguson's retirement in the summer.
The Scot was replaced by David Moyes, who left Everton to take up the job at Old Trafford, while Martinez moved to Goodison Park after four years at the Latics.
"I think he's the best manager in the world and I was a little surprised that Man United didn't come for him because I knew that Alex was going to retire," Whelan told Sky Sports News.
"Alex had already told me that he was thinking of retiring and I was a bit surprised that Man United 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."
Wigan are currently 11th in the Championship table.
