Son is a very limited player, and I think Jose's been working on that since he got here. I noticed a huge improvement in his tackling ability towards the tail end of last season, like actual blocks and tackles vs the rubbish he used to do under Poch.
His medium range passing, crosses, and flick ons also improved a lot. I think that's why he's become a bit shot shy. Just needs to remind himself that around the box he's still allowed to shoot sometimes.
Actually Kane seems the same, a lot less long range shots from nothing, which is practically his trademark.
