Swansea City boss Paul Clement says Manchester United pulled off a winning coup in the signing of Nemanja Matic.
Clement worked with Matic during his time as Carlo Ancelotti's assistant at Chelsea before the holding midfielder joined Benfica in 2011.
"I was surprised Chelsea let him go, I don't know how that deal managed to happen," said Clement.
"It's not too good for Chelsea and Antonio Conte has made it clear he did not want that to happen. It is a win for United.
"He is good positionally, he has good physical stature, he is strong in the challenge and good in the air.
"He has also a nice left foot and is an underrated passer and is very focused on his football."
