Ashley Barnes' knowhow of Gus Poyet tactics, which he has admitted to the Lancashire Telegraph, could prove to be an important weapon for Burnley when they take on Sunderland this weekend.
Barnes and Poyet worked together earlier in their careers - when they were at Brighton and Hove Albion - and the striker has revealed that he knows about how the Uruguayan likes to set sides up.
That could make a difference for Burnley as it will serve as an aid for Sean Dyche, as his team enter one of their most important fixtures of the season so far.
"They’ve got some great players there and I’m quite familiar with the way Gus plays," he said.
“He’s all about passing, keeping possession and we’re going to need to be at our game and defend for 90 minutes and score at the other end. We’ll go there and try and do that.”
Whoever wins at the Stadium of Light will take a massive step towards securing safety in the Premier League, while the losers are likely to end up in the relegation zone.
Burnley and Sunderland are both just one point above the drop zone at present and a defeat is sure to see questions raised as to their chances of survival.
Another three points on their current totals of 20 could propel them as high as 12th, though, and that is a tantalising reward.
Sunderland do head into the game as favourites, but Burnley's resilience has shocked many this campaign and the Black Cats will need to be at the top of their game if they are to pick up the three points in front of an expectant home crowd.
