I sometimes get him at the start, he's playing AMR for me atm, Mixed/Often FwD Runs, Often RWB, Long Shots, Through Balls and Crossing Rarely, although TB+Cross is sometimes mixed. Basically trying to get him to run with it then shoot or cut it back since he doesn't have great crossing ability, am hoping a few PPMs will make him come inside more.
Am currently trying to see how much creative freedom works best for him or if a FR would make him drift inside more. Also being able to play AML and ST is great for covering injuries, and his Free Kicks are alone worth it if you don't have anyone good at taking them.
Have to remember players need to play to develop, just leaving them in reserves and training won't make them reach there potential. Loaning is a matter of judgement, the specific training + reserve team football of your club vs the first team football and less specific lower quality training.
Got to remember players stop making big improvements in their physical attributes in the early 20s, if they're been left to rot during this time its time you'll never get back.
