Sunderland 0-1 Millwall: Duncan Watmore's strike keeps Millwall safe.

Millwall secured the Championship with Duncan Watmore scoring the winning goal against his former team Sunderland.

Sunderland posed a threat but were unable to find a breakthrough and ended up in mid-table.

The Black Cats, led by interim coach Mike Dodds, have not won at the Stadium of Light since defeating Plymouth on February 10.

Former Lion Dan Ballard nearly put the hosts ahead early on with a header over the bar from close range.

Millwall had a great chance in the opening 30 minutes, and when the ball came in from the right, Michael Obafemi ducked behind the front post and finally threatened. Luke O'Nien intervened and was able to get around and head into the corner.

The Black Cats opted to make a change after the break, bringing on fullback Trey Hume for Bradley Dack.

After an hour, Dodd made further changes, bringing on Abdullah Ba and Adil Ausiche.

A few minutes later, the two players combined well, with Ba passing the ball to Ausice in the middle, and Sunderland looked to take the lead, but was thwarted by a superb block.

However, it was the visitors who took the lead when Watmore curled Ryan Longman's cross into the roof of Sunderland's net.

It was Watmore's fourth goal of the season, coming against his former club after playing 87 games and leaving in 2020.

Sunderland complete the season with games against Watford and Sheffield on Wednesday, while Millwall host Plymouth before visiting Swansea on May 4.

Millwall manager Neil Harris told BBC Radio London:

“When I came here I had two objectives: to revitalize the football club and to get us over the dotted line.

“Both are equally important to me, Sunderland are a good team and it's very good to be three points behind them.

“We are not far from any team that dreams of finishing in the top 10. This is a great place to be.”
