You basically couldn't ask for more of a beast physically at the back. Thankfully he's finally gotten past the injuries like we all said he needed to do. Honestly think Jones can make a similar improvement once he stays fit, as he's also an excellent defender at his best and is only 23. That's a big reason why I think Van Gaal hasn't been too keen on buying a center back. He knows we have a top class one in Smalling, and a potentially world class one in Jones, and both are still a few years from their prime probably.
Ever since that red card a year ago, Smalling has cut out all the things that usually hold back young defenders, like the lapses in concentration, silly mistakes, and injuries, and over the past year, he's been as good as any center back around really. Not just the premier league. Definitely the best in the league overall though. This season he's finally started to get the recognition he deserves and he's been thriving since the start. You can see how confident he is in every game, basically dominating every player and bullying opposition players. He looks a lot more confident on the ball as well these days, and it'll only get better. Hopefully Jones stays fit and can form a partnership alongside him, because if so, then those 2, with Shaw at left back, should be 3 of the back 4 for England for a long time. Maybe Stones rotating in there as he has huge potential as well.
