Ben Doak is on the verge of a £25m move to Bournemouth – and while Celtic don't stand to make anything from his initial move, a little known FIFA rule may still pay out in the future.

Bournemouth have completed the signing of Ben Doak from Liverpool in a £25million deal. The Athletic previously reported that a deal was close with the south-coast club moving ahead of several top-flight rivals to try and seal a move for the 19-year-old Scotland international, with Liverpool including a buyback option as part of the agreement.
