It is clear that we are being built for the 2017-18 season, and this upcoming season is about Pep getting to grips with the Prem and making certain we are in amongst the Top Four for that year's Chumps Lge (and that we get into the latter stages this season), while hopefully winning a domestic pot!
I think that is the reason some still have worries. I personally feel we need to go for the title this season. Next season could be even more difficult with it being Mourinho's second season (that's almost like the title being given to him, even Pep couldn't stop him with Barcelona) and Conte's Chelsea would be a force with an almost unbreachable defense.
