The 37-year-old, who came out of retirement at the start of January, also claimed that Carrick is one of the most underrated players in the Premier League.
Despite winning four titles in his five seasons at Old Trafford, Carrick continues to divide supporters. However, Scholes has insisted that is not true among his teammates.
"Over the last six years at the club he's been terrific, one of the most under-rated players that the Premier League has had," said Scholes.
"Since he's come we've won the league in all but one season – that says it all. You need players such as Michael to be successful. He's a total team player, which players around him really appreciate.
"To be a central midfielder at this club you have to take responsibility – take the ball all the time, defend at times and be prepared to drive the team on to score goals and win games. Michael does all those things."
Carrick joined Manchester United from Tottenham Hotspur in 2006 for around £16m.
