Chelsea will be away at Old Trafford on Sunday, as the Blues get geared to face Manchester United for the third time this season.

Football pundit Martin keown expects a physical battle between Chelsea striker Diego Costa and United defender Marcos Rojo.

“It promises to be an explosive battle between Diego Costa and Marcos Rojo,” Keown told the Daily Mail.

“The United defender did not take any nonsense from Costa when the sides met in the FA Cup and there could be lots of fireworks on Sunday.

“Costa will be scratching his head as to why he has not been shortlisted for the PFA Player of the Year award.

“Rojo and Eric Bailly will need to have the games of their lives to stop him.”

He also predicted that Chelsea will win the game 2-1.
