10. Rowan Vine
Currently, Luton’s tenth most expensive signing in their history is forward Rowan Vine, who was signed by the Hatters for a fee of around £250,000 back in the summer of 2005 from Portsmouth after he had enjoyed an impressive loan spell with the club in 2004/05.
Vine was able to help the Hatters establish themselves back in the Championship in the 2005/06 campaign and he went on to register ten goals in 31 league appearances that term. The following campaign, the forward was unable to help the club survive in the second tier but he did manage to make 30 appearances in all competitions and score 14 goals.
That form was enough to convince Birmingham City to pay around £2.5 million for him in January 2007, but he only managed to score one goal in 17 appearances despite the Blues earning promotion to the Premier League. Vine was loaned out to QPR in 2007/08 and he scored four goals in 18 appearances before his move was made permanent that winter window.
The forward spent another four years with the Rs managing to score nine goals in 72 appearances. He was then transferred to St Johnstone in 2012. Vine has never really managed to be a prolific scorer for the rest of his career so far, with his best scoring season coming with non-league Hartley Wintney with ten goals in 2017/18. He is still playing though currently with Hemel Hempstead Town.
