Are you ready for some wonderkids? Joao Carvalho is first up. With a value of just £425k, he won't deplete your transfer kitty, and if you give him a few years to develop out on loan, he'll return as a fine player. The 18-year-old has all of the raw attributes to suggest huge things are in his future. He will develop into a fairly traditional pacey winger but he can be specialised to suit your needs. Patience will be key, but Carvalho is worth the risk.
