I know Taison, have seen him playing in Brazilian league. Above average/good player. I hope this doesn't go ahead because I want some attacking player to shine and make a difference here, not another squad player. His level is probably close to Sturridge's, except that he's more of a second striker. I admit I haven't seen him performing lately (in the last 2-3 years), though. So I could be wrong.
I think what people meant with "we don't need him" is actually "we need players for other roles more". I guess no one would complain about signing Isco if it meant we would still sign players for the positions we lack the most.
I know it is an YT compilation but wow. WOW! JAW-DROPPING ball control. If he plays like that on a regular basis, the guy is a monster of a player. 15m would be an absolute steal. However, he shouldn't be top priority.
That's when, IMHO, his movement (and other's movement, like Hazard) can help it the most. Off the ball movement can open spaces to the rest of the team and for himself. Constantly swapping positions confuses the oposition. The games I've seen him doing worse were the games he was limited to a small part of the pitch. Like when he was apparently ordered to fill Hazard role on the left wing. He was woeful in that game.
I have no idea if it has been posted before but I really like this analysis on Oscar: http://brazil.worldcupblog.org/world-cup-2010/the-playmakers-oscar.html
I think Oscar's problem is beyond adaptation to EPL. I mean, he's massive for Brazil even against strong opposition. I feel that he's been misused a bit. He has way less freedom in Chelsea, he drifts a lot across the field for Brazil and that's when he shines. Besides that, I've seen Oscar creating a lot of chances which have gone to waste because we lack a proper finisher. I feel his assists should be way higher than they are right now.
TBH I think this is going to be easy. If I recall correctly, when we drew with QPR, their GK, Julio Cesar, had a great performance, otherwise we would have taken the 3 points. But he's injured or something, isn't he?
My night was shit because things didn't work out with some belgian girl I have a crush on. Now I'm gonna join my fellow brazilians in the Hazard hate spreading. Just kidding folks (about the last part).
