Midfielder Michael Carrick says that the great Scottish tactician is the main reason why United players are so desperate to achieve success, especially after losing the Premier League title on goal difference to rivals Manchester City last season.
"The manager drives that attitude and it rubs off on the players," said Carrick after United clinched their 20th title on Monday night.
"To be honest, it happens quite quickly. If it doesn't, you are not going to be successful here.
"When I arrived, I tried to copy the example of the senior players. As I get older, I try to set an example for the younger boys."
Of last season, Carrick added: "It hurt and it wasn't pleasant but pretty much straightaway we started thinking about next year.
"It was said in the dressing room 'remember this feeling'. Even coming to the end of this season, we had a decent gap, but we didn't want to let it slip because we know what last year felt like.
"There are not many teams who could have come back from that. It was our local rivals, our big rivals. That did make it harder.
"But we got out on the pitch and started playing well, because we were determined to get back on top.
"I am proud of being part of that. The character of the lads is incredible."
