Birmingham City boss Alex McLeish has revealed Manchester United's dugouts can leave opposition managers at a disadvantage.
Big Eck recalls the first time he went to Old Trafford in charge of Rangers.
He told the Scottish Sun: "It was great to go to Old Trafford for the first time as a manager.
"At the start, I probably didn't interact with the players as much as I should have.
"The seating area for the coaches and subs is in a strange place away from the track and it was sort of intimidating. But I very quickly realised that I had to make sure I was getting up and down and getting messages across to the players.
"It was a good lesson for everybody and, of course, I'm now going back there every season with Birmingham City in the Premier League."
