The Scotland striker held the Scottish transfer record for all of six days after completing his move to Bramall Lane last week.
The former Nottingham Forrest youngster broke the landmark fee for a Scottish player twice in the space of a year. First, his 2016 move from the City Ground to Germany cost Leipzig £13million. They then sold him on for a profit when he joined the Baggies the following summer.

The striker’s 2016 switch from west London to the West Midlands took the total of his transfer tallies to £23.47million but it is unlikely the Villa faithful will see it as money well spent after seeing the ex-Rangers, Cardiff and Leeds poacher net just three times in 24 appearances.
The Gosport-born winger dropped down from the Premier League to the Championship when he joined the Magpies in 2016 but he would be back in the top flight a year later as Rafael Benetiz’s men stormed to promotion.
