Sunderland striker Steven Fletcher has told the club's official site about the improvements that Dick Advocaat is trying to make at the Stadium of Light.
Advocaat was appointed by Sunderland to replace Gus Poyet earlier this month and from Fletcher's comments it seems he has wasted no time in asserting his influence.
Fletcher says that Advocaat is trying to work on their attacking play, but he wants them to be far more compact as a team than they were under his predecessor.
“He wants us to play a lot more compact and push forward as a unit," Fletcher said. "I think we did that in the last game [against West Ham] because we won balls back and created chances.
“It’s been really lively since the new coach has come in; he’s a lively character and he’s brought that into the training sessions. He wants us all to give 100% and believes we’ve got the quality to turn our fortunes around and push up the league."
Advocaat needs to hope that his proposed changes take effect soon, as he has little time to waste.
Sunderland are in the heart of a relegation battle and if he cannot get them to improve on their showings during Poyet's regime then they are in serious danger of facing the drop.
At the moment the Black Cats are one point above the relegation zone, but it is far too slim an advantage to feel secure with.
It means that Advocaat's appointment simply has to work for Sunderland and Fletcher will be hoping that the rest of the squad are enjoying training under their new manager as much as he is.
