cameo at Southampton in United’s last game.
The pair have spent two decades under Sir Alex’s tutelage and the boss counts himself fortunate to have been able to work with them for so long.
"You can’t judge Ryan’s performances at the moment because I haven’t played him!" said Sir Alex. "But he will be involved in a lot of games this season, as normal, and I’m sure we'll see his ability.
"Paul came on against Southampton and it was like opening a door to another room. He brought order to the game. His selection and accuracy of passes changed the game.
"Robin van Persie, quite rightly, said he thought he was the man of the match, even though he was only on the pitch for 25 minutes. Southampton didn't know what to do with him.
"That's a great credit to the lad. He'll always produce quality. He could be playing in 10 years in a former players’ game and still show what a fantastic player he is.
"I'm lucky to have worked with them both. It’s not a matter of being proud to have had them. It’s more a matter of saying, 'I'm lucky to have had two devoted players like that'. It's been brilliant."

"It's a landmark for the three players and it's a great example to the younger players about what can be achieved if they sacrifice in football."
