Former Blackburn Rovers midfielder Robbie Savage rates Tugay as the best he played with.
Savage played with Manchester United great Ryan Giggs for Wales.
But he told the Daily Star: "Tugay was an incredible player, one of the best. He could have played for any team in the world, in my opinion.
"He was unbelievable, even at 37 or 38 in the Premier League, he was still brilliant.
"Even the top players from other clubs wanted to get Tugay's shirt, that's how good he was. He was incredible, could have played in one of the big-six in the Premier League.
"(In training) Unbelievable, the best. You ask anyone who played for Blackburn in my era, they will all say Tugay. We had some wonderful players, Roque Santa Cruz, Craig Bellamy, David Bentley was great for a while, Benni McCarthy.
"You ask all those, and they would all say Tugay."
