You say frustrating, I say utter, utter garbage. His career stats are pathetic.
Over his PL career it's basically 1 goal in 20 games and 1 assist every 10!!!!
Every time he got on the ball commentators would raise their voices in anticipation of something happing. They'd be better off making a brew.
Same story as that showpony Newcastle just sold to Saudi Arabia, (1 goal in ten, 1 assist in 6) Listen to the media and you'd swear they're talking about prime Ronaldinho. His PL career stats are more or less exactly the same as Demarai Gray. (slightly worse, infact.)
Gray has been the only Benitez success, but if we make a decent profit on him he needs to move on and be replaced by a player better suited to how Dyche wants to play.
