If young players are capable of playing 90 minutes every week at European clubs why prevent them from doing that?

There are many clever contractual ways to let a young player continue his career elsewhere while still having first option to bring them back in future. Contracts can include a buyback clause such as Barcelona had with Cesc Fabregas, or a sell-on clause where the development club benefit financially from all the work invested in the young player.

Sometimes clubs take their ownership of a young player for granted and do not necessarily do the best thing for their development.
