You'll probably get some grief for that post from some of the resident experts on here, but based on the players we're looking at my biggest fear is that we'll be bullied out of the trophy hunt next season. I know height and muscle don't count for much in some leagues, but they are an important aspect of winning consistently in the PL, and you can usually measure the difference between going to places like Anfield and losing horribly every single year like we do (Navas, Sterling, Silva and Aguero this year was an utter lightweight fucking disaster), or going there with a team of 6ft juggernauts and winning there like the rags always do, in actual inches and pounds.
What every squad needs of course is a balance. We had height, weight AND flair in 2012, but last season we were lacking physically IMO. Stones, Nolito, Sane, Thiago, Gundogan, they're fine players, but in a squad that already includes the 4 attackers I named earlier, we absolutely need some height and power as well, or we will win fuck all next season, however good Pep is.
