Ryan Giggs gives three reasons why Michael Carrick is so valuable to Jose Mourinho

Ryan Giggs believes Michael Carrick has been on the Manchester United coaching staff for years.
 
The United legend, who hung up his boots in 2014, returned to the Old Trafford turf for Carrick's testimonial match in front of a crowd of more than 70,000 people.
 
Midfielder Carrick has signed a one year extension at United, but has already started doing his coaching badges and doing some work with the club's under-9 side.
 
But Giggs believes he has been helping his teammates perform at a higher level for years.
 
 
“Michael just makes players around him play better," Giggs told ITV.
 
“He’s got that calming influence that you can see on and off the pitch, it’s a pleasure to play with him.
 
“When you play with players, you want to trust them when they have the ball and Michael is one of those players.
 
“When he is on the pitch, you can trust him. He always makes the right decision.”
