Sunderland’s Millwall preparations have been hit by heavy snow this week.

The Championship strugglers travel to the Den on Saturday looking to close a five-point gap from safety.

Snow has caused disruption across the UK since Monday, and Sunderland were forced to cancel training on Wednesday due to the adverse weather conditions.

Speaking about Millwall, Black Cats boss Chris Coleman said: “They are a tough team to play against, very well organised.

“They are not afraid to play ugly when they need to, which is a feather in their cap.

“But they also play good football, and Neil Harris is doing a real good job.”

Millwall are seven points from the play-offs after extending their unbeaten league run to eight games against Burton last weekend.
