Just look at him play and you'll see the extreme difference from Gestede for exampel. Gestede could head the ball and not much more else... Watkins works extremly hard, never misses a game, 26 goals from open play last year, has pace, can do a job on the wing. But, most of all he will be extremly important in the defensive work. He will be great at starting the press from upfront and will do that job for 90 mins. Theres more to a strikers game than score goals in modern football.
I'd say Watkins is the most important signing we could do this summer. If it cost 28 m£ with addons then so be it. I dont think we could sign at striker from Europe with all of Watkins upsides for the same amount and is willing o come to us.
