So that aerial stat % does not mean much. Azpi for a fb is fine aerially but against set pieces, your position mean nothing, and is he good enough to defend against tall striker, clearly lamp say nope and clearly he said yes about alonso.
I think there is this view that our set pieces defense problem is only because of lamp, that he is just so bad at organizing set pieces and that the fact that we have many small player and very few aerially good player isn't the reason. So it is ok to have small team and just by being organized, we will be very2 good. I clearly remember everyone said the same thing about klopp. He can't coach set pieces. VVD, matip n Fabinho later no one talked about it anymore.
Now, our team instead of getting aerially better player, we replace our tall player with smaller player, and we think it will get better next season.
