Michy Batshuayi scored twice as Chelsea made short work of Grimsby Town in a 7-1 demolition of their League Two opponents in the Carabao Cup third round at Stamford Bridge on Wednesday night.

Ross Barkley scored in the fourth minute, Batshuayi struck his first in the seventh and Pedro added a penalty kick to give Chelsea a 3-1 lead at the break.

Goals from Reece James, Callum Hudson-Odoi, Kurt Zouma and Batshuayi's second took the hosts to the final 7-1 scoreline on an easy night for Frank Lampard's side.

"We got some players who haven't been playing so many minutes, players that are younger, starting the game," Lampard, who also also brought on two debutants in the second half, said.

"A nice comfortable win having not won here yet so on those levels, of course I am happy."

The result sets up a juicy fourth-round match for Chelsea against Manchester United, the first such meeting between the two clubs since they met in the fourth round in 2012-13.
