He hardly shone in the Championship last season, he should go play for Luton Town on an affordable wage.
This is the problem, you get players who have a lot of talent - if they dropped down a league on affordable wages they'd get a chance and then if they shine - a top tier club would come in for them, but nah hardly any clubs in the Championship can afford him hence he's a free agent, you can't expect clubs to gamble on players with form for being injury prone.
I remember when Chelsea's had a young player called Josh McEachran who was also highly rated, he now plays in League One.
A young player comes along, shows promise, we immediately start comparing them to established world class footballers, they hype builds, the expectation builds add the two together and we get - pressure, that young player can either thrive on it like Ronaldo with an obsession for being the best - or they can start believing they are the best before they actually achieve anything of note and this more often than not leads them to stagnating, some get to 25 and have started less than 50 first team games,
Young players need protecting, it's telling that this mostly occurs in England rather than clubs abroad,
Credit to British players who have decided to go abroad like Bellingham, Sancho and a few others that play in France and Germany, they rolled their sleeves up, embraced a new culture and were willing to learn, credit to the foreign clubs who were willing to give them a chance too.
If Jack wants to come in and work with the youngsters, do his coaching or use the facilities to get himself fit then good luck to him but unless he has a glass of port before every game we will never see the fearless player we remember.
