Sir Alex Ferguson has hailed the signing of Michu, while lavishing praise on Swansea's own exploits this season.
Michael Laudrup's side snapped up the striker for just £2 million last summer, and the Spaniard has proved to be one of the signings of the season, hitting 19 goals already.
Swansea themselves have also impressed, with Laudrup guiding the Welsh club to their first major honour, winning the Capital One Cup last month.
"Swansea have been terrific," Ferguson said on Manchester United's official website. "The boy Michu has been a revelation. To sign him for just £2 million and get 20 goals [19 goals] out of him - what a bargain!
"I wouldn't say Swansea have been the surprise package but they've really lifted their performances. They were a newly-promoted side last year and managed to survive in the top flight. This season, they've kicked on to another level and become a good middle-to-top side.
"They also won the League Cup of course and they play really good football. I'd say they're the team of the year with Michu a real bargain buy."
