He has been doing well for a while now, in most things except scoring. Same for the national team. He puts in tons of work now and uses his body well to create space. He is only lacking better ball control.
and finishing
and link up play
and shooting
and passing
i agree though, he does work a lot. i thought that playing to counters would benefit him, and it actually did because that's how he got thiaw sent off. physically he's in very good shape, he moves well, he's quick, his ball control isn't actually that bad, see that episode when he managed that 2 m high ball. it's a bummer and a bit ironic that the last time he scored a screamer from distance (and it was disallowed for offside), but he couldn't find the target from 2 meters against milan.
he'd need the capello treatment that zlatan got: additional shooting practice every day for half a season. if he can't improve his finishing then sell.
