I’m not sure what his age has to do with anything, this is first team football and he should be judged the same as everyone else. He’s here to develop his game but he also needs to be good enough in the here and now to contribute to our immediate objectives.
There is nothing wrong with making an observation that he isn’t quite ready yet, I think it’s a fair one. Everything he does defensively seems very erratic and rushed, he does get up and down the flank well but rarely looks like putting any kind of delivery into the box, let alone a threatening one. I think he needed an extra season of two in Holland before making the step to the toughest league in the world, maybe we could loan him to Lorient next season if they stay up? Get the impression with him that the jump was too big and too soon. Having said all of that I feel like he will come good in time, he has the ingredients he just needs a bit of polishing.
