Arsenal manager Arsene Wenger believes that Manchester United's ability to see a game out could be key to them winning the Premier League title.
The Frenchman does not feel that United have been at their strongest throughout the season but points to their greater experience as an advantage over second-placed Manchester City.
"Manchester United are surprisingly in a comfortable position, no-one expected them to be because they did not look absolutely irresistible this year," said Wenger.
"You could see that again on Monday night against Blackburn, but they managed to win the game. If Manchester United make it to the title, it is really down to experience."
Wenger added to this by saying that United's habit of winning games in the latter stages is something that City haven't quite mastered yet.
"At Blackburn when [Ryan] Giggs came on in the last 15 minutes you thought 'they can only win it now' because they know how to deal with the money time, that means the last 15 minutes in football when it is 0-0," he said.
"They don't make a mistake, they have that security at the back. United have won so many titles because they are not nervous."
The Gunners face United's championship rivals City at the Emirates Stadium on Sunday.
