Chelsea made a mistake in loaning Ruben Loftus-Cheek out to Crystal Palace, according to Willian.
Loftus-Cheek joined Palace on loan in the summer, and has impressed despite the south London club’s slow start to the season.
He was rewarded with his first England call-up during the latest international break, and started both games against Germany and Brazil.
The midfielder proves that the loan route can lead somewhere, despite Chelsea’s oft-criticised system with regards to younger players.
But former teammate Willian has questioned why he was loaned out in the first place.
“He’s a very good player. He is strong, he has quality. He has a great future,” said Willian.
“I don’t know why he is at Crystal Palace now. I don’t know why. He has to come back.”
