We have a 20% total fee sell-on clause (not profit as reported by some outlets), so if he did make the England squad and Bournemouth flog him for £40m+, we'd have a nice little pay day. Can't find anything about a buyback. Mad considering given the initial fee and add ons, Bournemouth have ended up paying us £24m for Solanke. Based on his record since, he probably isn't worth all that much more than that despite his excellent record in the Championship.
Amazing bit of business really, make £24m profit, Cherries flog him to Villa or Brighton for £40m, we make another £8m on him.
