NEIL Harris admitted Sunderland's awful home form could offer Millwall an advantage on Saturday – but warned the Black Cats' luck in their own backyard is bound to change at some point.
Sunderland haven't won at the Stadium of Light in almost a year, since a 1-0 win over Watford last December, matching the English record of 19 games without a victory at home.
In Harris' first season in full charge the Lions lost four successive league games at The Den from the start of the season, before they turned that form around.
All of Millwall's wins this season have come at home, but they are still looking for a first win on the road.
Harris acknowledged it is difficult to find a solution when results are going against a side on their own patch.
"It's really tough to change a mindset," he said. "We found that here. We finished a season flying at home winning massive games against Wigan and Charlton and drawing against Derby who were in the play-offs at the time, and you think you've cracked it.
"Then we start the following season and we lose the first four in a row at home. It's really tough.
"We can use [Sunderland's home form] to our advantage. The law of averages says it will change for them at some stage – we've just got to make sure it's not Saturday."
Meanwhile, the Millwall players on international duty this week – George Saville, Shane Ferguson, Aiden O'Brien and Conor McLaughlin – will re-join the squad for training on Thursday.
Harris has been pleased with the work the squad have done since the 1-0 defeat to Burton before the international break.
"The boys have been excellent, we've had a really good period," Harris said. "We've missed the boys who have been away on international duty, the personalities of George, Aiden, Fergie and Macca, they're great lads. It was great to have Jordan Archer back in on Monday, he brings a different dimension to the group.
"We look to have those boys back Thursday fit and raring to go.
"We're looking forward to Saturday. It's a fixture you look for at the start of the season, Sunderland away. It's a great one."
