Brighton & Hove Albion boss Graham Potter has lauded the work of Marcelo Bielsa at Leeds United ahead of Saturday's clash at the Amex.
The Whites travel to the south coast hoping to avenge a 1-0 defeat at Elland Road earlier in the season.
Potter has earned plaudits for improving Brighton's style of play, though the Seagulls have struggled to turn chances into goals and, as a result, they are still fighting to secure their Premier League status.
Leeds have no such concerns and come into the match unbeaten in six matches, in a run that has seen them face Chelsea, Manchester City, Liverpool and Manchester United.
Speaking ahead of the match, Potter hailed the work of Bielsa in transforming the fortunes at Elland Road.
"I think he has done a fantastic job and everyone at Leeds United has done really well," Potter told SussexLive.
"It’s great to have them back in the top flight, it’s a great football club with tradition. The way they have taken on the challenge doesn’t surprise me, I knew they would carry on playing the way they play.
"It always makes me smile a bit when teams have success doing something and then they change when they get to the top and I knew that wouldn’t be the case for Leeds. Congratulations to them.
"Historically I have been aware of his teams. I haven’t had an in-depth look at his methods in terms of how his teams train. His Bilbao team I remember playing at Old Trafford and doing fantastically well, his time coaching the national team.
"One of my first games back in the UK was against Leeds United, it was our first or second home game. He’s not someone I am necessarily familiar with, but he is someone that I have followed and have huge admiration for."
"Whenever you play Leeds it’s a dangerous time, they’ve proven that over the course of the season, full credit to them. Marcelo (Bielsa) is amazing," he added, when asked if this was a bad time to face Leeds.
"Whenever you play them it’s dangerous, they’re capable of beating anyone, they can win any game. They’re a strong team and we need to be ready.
"They’ve been together for a few seasons, they’re well organised and know what they’re doing. They’ve got threats all over the pitch, they can attack you down the sides, through the middle.
"The intensity they play at has been well documented. They play with aggression and if you don’t match that, then it’s going to be a tough afternoon."
