We sold schurrle who has a natural scoring abillity and brought in this guy (his stats show that he's really not a goalscorer). I'm a bit worried although he does seem to have a good shot, blistering pace and trickery. Seeing how Schurrle wasn't really involved this isn't that bad.
One goal and one assist in 21 PL matches this season so far.. The balance that he brings and his defensive contribution wont be enough to keep him here for long IMO.
He's something special.. but his defending is horrific at times. Never closes down the wide man, lets players cross with ease, never to be found in the right place in situations like the Moreno one.
