That's been our way for years - buy, develop, sell, repeat. There can be a painful and slow development period - eg Salisu - but quick ones - Tino - or abject disasters - Hoedt - etc etc.
The thing with Lyanco is that he didn't feel like the our usual type of investment signing. It felt like a cheap punt which may or may not work out. The reviews from Italy were underwhelming, thus posters who read those, were underwhelmed. So far he looks better than expected, and our coaches may be a part of that.
