I am on record predicting that he won't be a super-star for us but I think he had, overall, a very good game for us, despite the ill-timed and poorly-executed shot (so what, SG had a couple of those, as well) and a bit of timidity on the defensive end in the first half.
I thought he and Jonjo played remarkably well in what became a 442 with Downing and Gerrard on the 'wings' in the beginning of the 2nd half. I thought we gained nothing by having him and Gerrard paired up in CM after Jonjo was inexplicably substituted for.
He has some 'mental lapses' every now and then which, for a young player with quite a bit of talent, he should work on reducing to an absolute minimum. Like everyone else, he will make mistakes but not being 'in the game' is near inexcusable, given how much actual Premiere League experience he has.
His passing was excellent, both short and longer-distance. Like Lucas's his longer-distance shooting is "over-thought" and "over-finessed". Both of them need a bit of Jonjo in them, while the latter needs quite a bit of the Lucas and Hendo yeoman-like application and methodical character.
