Sebastian Larsson has spoken positively of the impact Dick Advocaat has had at Sunderland.
The Dutchman took the reins at the Stadium of Light on March 17 after Gus Poyet was sacked and managed to guide the Black Cats to a famous 1-0 victory over Newcastle United in the Tyne-Wear derby on Sunday in just his secnd game in charge.
"It's difficult when you've got a short time to change things too drastically," said midfielder Larsson.
"He's come in and told us what he wants us to do and how he wants us to perform. He's told us we've got to show that passion. There was some half-decent stuff."
