If Hernandez can really work on his crossing, and if his decision making improves to be a little quicker. He'd be one hell of a player.
His crossing is a bit iffy, and he does hold on to the ball and try to do to much too often. So ends up running into a corner and getting crowded.
Everything else though is class, and I love to watch him play. He is so exciting, and under the cosh, like at home to Hull. Every time he got the ball, he would sprint forward and it made me feel so much calmer. He was such an outlet. I knew, if he got it in our own half, we would be at their touchline in about 30 seconds with a chance of a goal, throw or corner to take the pressure off our defence. That's been really important.
At this level he is proper class. I just think, to step up to Premier League standard. Crossing and fast decision making are the main things he needs to work on. Nail them, and my word he'd be incredible.
