Loftus-Cheek was sent out on loan this season to Crystal Palace in order to gain more first team experience.
He ended up earning a call-up to the England national team for recent friendlies against Germany and Brazil and made his international debut against the 2014 World Champions and won the man of the match award in the 0-0 stalemate.
“I don’t know why he is at Crystal Palace now – he has to come back!” Willian said.
“A very good player. He is strong, he has quality. He has a great future.”
