Viduka scored 92 goals in 240 Premier League appearances for Leeds, Middlesbrough and Newcastle and admits that he has been pleasantly surprised by Bielsa's success.
“I was rapt when Bielsa was appointed as manager. I heard a lot of good things," he told Sky Sports.
“To be honest, I didn't expect him to have such a big impact. It just goes to show that someone who can take a team like - OK they were a better team in the Championship - but to be up in the Premier League and play the type of football they play. It's very exciting.
“I enjoy watching Leeds and I like his philosophy of attacking. The way that they play, you can tell they've worked really hard at the team's cohesion, pressing as a team.
“It's just exciting football. Nobody likes when you lose, but I like the fact that they all put 100% in. They work together as a team."
