I think it's obvious Chelsea are going through a defensive rejig more than anything, 2 players are above 30. They need to bring Azpilicueta in at the right, a fast left back to help Hazard, which they are doing. It's going to interesting to see who the cbs will be over the course of the season?
regards to good football, you can only really expect a title winning team to win and play well like 40% of the time, premiership is harder as well because of the competition, Barca, Bayern might have done more in the past because of the lob sided league. There are going to be games which you have to scrap through.
None of which addresses my points.
Chelsea's defence may be reorganised this year, but signing one defender won't see massive changes and we don't even know how good he'll be. £20mil for a left back playing for a not particularly strong club screams of the current massive overpaying for anyone that is going on.
More importantly the last part. Champions don't always play well, there are always games you'll have to grind out however that isn't what we are talking about with Chelsea. What you are talking about is over a season having randomly bad games throughout the season, but having good games throughout the season. Few if any teams manage 95% great performances, but few champions manage to play dismal football for one entire half of a season. That is the difference, Chelsea didn't have the odd bad game last year, they started off offensively strong and regressed throughout the entire year, the last 3-4 months they looked horrible repeatedly.
But again the main point of my post was, Mourinho's teams ALL do this, every time. He takes over and the team gets progressively worse offensively, more defensive and overall less good. Happened at Chelsea, happened at Inter, happened at Real where people constantly talk about how their offence frequently doesn't link together. Without Ronaldo that offence would be a disaster.
Every team he leaves also tends to go through a recovery period to some degree. In Chelsea's case they spent year struggling to find consistent offensive balance and a lasting legacy has been Chelsea have been overly defensive due to the style Mourinho instilled on the spine of the team that stayed there for so long. Every manager that came in after Mourinho was effectively tasked with improving the offence and breaking the defensive mentality of the squad.
If Mourinho does this at every club, has done it previously at Chelsea, if the team clearly regressed over last season to be almost two different teams, why do people believe he'll turn it around. Maybe a more pertinent question is, which overly defensive side with a misfiring offence has he turned around previously? He's fixed a poor defence repeatedly, I've never seen him improve an offence so why do would anyone believe he'll suddenly do that now?
