Bought for by Leeds United £6million after a protracted transfer saga during the summer of 2000, the Australian was finally awarded a work permit to take his place as the big striker the club had been chasing for some time.
Voted the Scottish Premier League Player of the Year in 1999/2000 after scoring 27 goals in his first full season at Celtic, after another transfer saga in 1998/99 following his arrival in Britain had curtailed his appearances in that season.
Tall and powerful, he started his career in Australia with Melbourne, before moving to Croatia Zagreb, by virtue of his Croatian parentage, and then joining Celtic in a £3.5million deal.
When joining Celtic he was actually known as Marko Viduka, until his agent requested us hacks drop the 'o' from his Christian name!
His move to Celtic was held up as 'Marko' claimed he was under stress from the war that had taken place in Croatia He returned to Australia to get his head together.
Made his Premiership debut in a 2-1 win at Middlesbrough but had to wait until the end of September 2000 to net his first goals - a brace in a 4-3 win at home to Tottenham.
Went on to net four against Liverpool in November and is now an established striker in English football. Scored an impressive 22 goals in his first season.
Season 2001/02 was nowhere near as fruitful, and Viduka would only score 16 goals this time around. He was constantly linked with a move to Serie A giants AS Roma throughout the campaign.
That speculation did not die away in the close season as Leeds looked to sell to solve their cash flow problems, but by the start of the 2002/03 season he was still a Leeds player. By then he had scored 38 goals in 95 games for the club.
