Memphis is what, 21?
A young kid, away from home for the first time, in a new Country and new League which is a big step to what's he's used to with massive expectations on him and a sizeable fee. Kid has considerable talent but he's naturally not only gonna' take time to settle and adapt, but he's gonna' go through the ups and downs most young kids go through. Seems like a nice dude who's well liked by everyone.
He's just getting magnified because that's what happens in today's transient World with big fees and expectations. People want instant success.
Maybe he struggles to adapt and ultimately goes somewhere else. Maybe he turns into the player his talents suggest he could be. But it's WAY too early to be criticising him and holding him up to such high expectations in an ideal World. Pity he can't just naturally develop without the added pressure as he was a great looking long term prospect that you hope would be able to contribute early in spells as he grew.
Nothing much to see there right now. Just a young player slowly finding his feet.
