I hadn't seen anything of him before he signed for us, so I'm only going off what I've seen this season, but his game appears to be built around very quick decisions and first time passes and shots. When things go well, this leads to tons of goal-scoring opportunities and consequently a lot of goals, but if he's a little off, those quick passes tend to go astray and he's reduced to basically giving the ball away a lot.
id agree with this, a lot of his potency comes in very quick bursts of outstanding quality, resulting in goals/assists/dangerous build up. His general play around the pitch is actually not very spectacular and he is careless in simple possession. But, as me and a mate were saying, he produces a lot at the business end which is where it matters!
