Chelsea ace Willian has declared Alvaro Morata and Eden Hazard as "world class".

Chelsea's top scorer Morata linked up well with Hazard as the duo helped Antonio Conte's men rescue a point after squandering a 2-0 lead against Roma.

"They are great players and have great quality," Willian told the London Evening Standard. "But they can improve more."

He added: "I think now we must improve and to try and win the other games."

Chelsea remain top of their Champions League group.
