Swansea City boss Paul Clement has explained why Chelsea sold Manchester United midfielder Nemanja Matic to Benfica.
Clement worked with Matic during his time as Carlo Ancelotti's assistant at Chelsea before the holding midfielder joined Benfica in 2011.
"I was not sure about him when I worked with him, and I don't think Carlo was because he did not play much," Clement said.
"But at that time Chelsea had a really strong midfield - John Obi Mikel, Michael Essien, Frank Lampard and Michael Ballack.
"So it was always going to be hard for him to break in and the club decided to sell him to Benfica. But he did really well and they got him back in the end."
