The highly-rated forward was brought to the club by Gary McAllister in the summer of 2008 and has become a firm favourite at Elland Road.
Having captured the attention of a number of English clubs while playing for Livingston and then on loan at Stirling Albion, Robert had no doubts when Leeds United came calling and he joined the club at the end of July 2008.
A Scottish youth international, he scored 10 goals in the Scottish First Division the season before he moved south and his pace and goalscoring ability caught the eye. He was linked with a move to Barcelona at one stage, following suggestions that the Spanish giants wanted to take him on trial.
Robert is still a relative young player but he made a big impression during his first season with the Elland Road club. Rob made his United debut at Scunthorpe in August 2008 and scored in the Carling Cup win at Chester City four days later.
He has scored some stunning goals, including a scissor-kick against Northampton to bring up the century for the season, and he deservedly picked up the Regional Members Clubs' Player of the Season Award in 2008/09.
The Scot was rewarded for his efforts when he signed a new four-year contract with the club on the eve of the 2009/2010 season.
He followed that up with another strong season in 2009/10 when he sailed past the 100 appearances mark as the club clinched promotion to the Championship.
