He's an average impact sub. I'd sooner we try and invest in a quality, tried and tested centre forward and leave DCL and Tosun to fight over the "impact sub" position. The sooner we can get shut the better imo.
For the 30 odd million Arnautiutuueutovic is being quoted for, I'd be in there too. Can play up top or wide left/right, and has pace, strength and certainly knows where the net is. Would also weaken West Ham.
I'm just kind of hoping we have something better in the bag though. No doubt its going to be a long January.
