I don't understand this. If he's not signed a professional contract then he's a free agent anyway isn't he?
He's still under scholarship, so the buying club would have to pay us a development fee. And surely he must realise that going on strike doesn't look good to his potential new club anyway - are a club really going to spend millions on a 17 year old who could end up going on strike again in 2-3 years to try and leave them?
