I agree with ATLIS completely. We have got a fee for a player who appeared to no longer want to be at the club (turned down new contracts) and have secured a sell-on clause in case he continues to shine. We have at least two players ahead of him in that position, in addition.
This is going to continue to happen until we consolidate ourselves in this league and grow the fanbase - these should be our next aims. There is no reason why we can't aspire to be like St. Johnstone, provided we get our act in gear off the park.
Byrne gave us three good years and lots of great memories. Best of luck to him in the rest of his career.
