The 33-year-old is currently playing for Lech Poznan in Poland and has been a consistent performer for the likes of Leeds United and Blackburn Rover, but has only made one international appearance coming on as a substitute for Andrew Robertson in a 1–0 win against Hungary in 2018.

The Motherwell boss made his one and only appearance in November 2004 under caretaker manager Tommy Burns in a 4–1 friendly defeat to Sweden, coming on as a 54th-minute substitute for Hearts centre-back Andy Webster. Photo: jeff holmes
The Hibs assistant manager made his Scotland debut in 2004 during a 4–1 friendly victory against Trinidad and Tobago at Easter Road. He was called up a further two times, in 2008 and 2009, but did not get on the pitch. Photo: SNS Group Alan Harvey
The current Hearts boss played for Scotland under 21s a total of 10 times but won his first and only full Scotland cap in a 2–0 UEFA Euro 2008 qualifying defeat to Ukraine in Kyiv in October 2006. Photo: SNS Group 0141 221 3602
