Former Manchester United assistant Mike Phelan believes David Moyes will overcome the early hurdles he has faced since succeeding Sir Alex Ferguson as manager, and has backed the Scot to have a long and successful career at Old Trafford.
For the first time since 2008, Phelan was forced to watch from the outside, as the reigning Premier League champions made a mockery of the summer transfer window, failing to land a number of their high-profile targets.
Fergie's right-hand man admitted the club were slow to react to other clubs strengthening their squads during the close season, but is confident Moyes will learn from the experience and improve in the future.
"When it comes to the transfer window they were probably a bit slow in reacting to the market," Phelan is quoted by the Daily Mail.
"Due to United winning the league comfortably last year, I'm not saying they were resting on their laurels but the fact is every other club was not going to let that happen again.
"To close that gap they had to spend big. United will always be in for the right quality player that not only comes into the club but also goes straight into the team."
During his time as Ferguson's number two, Phelan helped Manchester United win three Premier League titles, a Club World Cup, two League Cups and reach the Champions League final twice.
This season has been a slow start by comparison, with the Red Devils dropping eight points from their first six games, following away defeats against Liverpool and Manchester City, and a draw at home against Chelsea.
Even so, Phelan is backing Moyes to handle the pressure, and expects Manchester United to make up the five-point gap between themselves, and Arsenal and Tottenham, at the top of the Premier League table.
"He's not been at the top level for as long as he has without gathering all the experience to deal with these situations," Phelan added in a talkSPORT interview.
"I'm sure he'll stand up and be counted like the rest of the squad. It was a poor result against Manchester City, getting beaten in a derby is not the end of the world, but it's how you perform.
"David will realise the magnitude of the job and the players available."
