Michael Carrick says it must be 'horrible' to have to defend against Antonio Valencia, following the winger's dominant display in Manchester United's weekend win over Bolton.

Valencia ran the Trotters ragged at Old Trafford; creating five clear opportunities for his teammates in a 3-0 win for the Barclays Premier League champions.

The 26-year-old has been in fine form indeed this season, and contributed an impressive seven assists during the month of December.

And, following Valencia's most recent swashbuckling performance, Carrick was quick to praise the fleet-footed Ecuadorian.

"He's really on his game at the moment, and has been for a good number of matches," Carrick told the official Manchester United website.

"We just keep giving him the ball and he carries it up the pitch and creates opportunities for us.

"It’s great to see him playing like that and it must be horrible to play against."

The former Wigan star also received praise from Patrice Evra, who was in awe of Valencia's display against Bolton on Saturday afternoon.

"I think he ate a motor," said the French defender. "He was unbelievable.

"I don't know the left-back of Bolton [Sam Ricketts], but I'm sure he had muscle problems after the game. Antonio's so powerful."
