I thought it went to a tribunal for us with Sturridge because his contract expired and as he was under 24 years so we got a developement fee that had to be decided by tribunal as we couldn't agree one with Chesea. A similar scenario to yourselves getting Ings from Burnley. If you can't agree a deal with Burnley it will go to tribunal. I might be wrong though I'm no expert I just saying what I perceive the situation to be.
Unless of course it counts that you have developed Sterling as you bought him when he was 16. Like I've said I don't know.
Yeah my understanding is that we would get the development fee from Sterling the same as you with Sturridge. He was 15 when he joined Liverpool.
