Not a snowball's chance in hell that Klopp will treat the CL with less attention than the league. To be honest I'm struggling to see what makes you think that would happen? Remember the ocean full of scorn that Rodgers received for starting a second string side away at Real Madrid? Klopp will be throwing everything at that competition and rightly so.
Indeed and on top of that, look at his Champion's League record with Dortmund. He did amazingly well with them and still did well in the league too. There's no way he drops the CL. If anything, he'll drop the League Cup as that comes together with all the group stage games and I think the busy December period. Our progress in the CL will also determine how we treat the FA Cup probably.
At this point it's City's to lose. Guardiola's second year, the huge amount of money they have invested in players to suit his system and style of play, Kompany seemingly fit again, the quality of all their attacking players, ... Anything other than winning the league will be seen as a failure for them in my eyes.
I'm not that worried about Chelsea. A lot of people have pointed to our lack of squad depth, but how about Conte's squad then? As it stands, Conte has a squad of about 15 players (counting the injured / suspended ones) to choose from. No Hazard and no Costa, two of his most important players last season. Everyone says they have strenghtened, I don't agree. If anything, they look weaker. If Conte refuses to play Costa, it's going to cost them dearly. He might be an utter c**t, but he's a brilliant striker. Even though I really like Batshuayi, him and Morata don't even come close to Costa. Other than that, there are just like for like replacements in Rudiger for Terry and Bakayoko for Matic. They looked pretty poor in preseason too.
Same with Spurs, they have a brilliant starting eleven, but their bench looks so poor. The only good bench option they have is Son. Walker gone and now their stand-in RB is Walker-Peters (?). Still no replacement for when Kane is injured either. Their record at Wembley is poor and if they don't bring in players, it's going to be a very long season for them if they get hit by injuries.
Not really worried about Arsenal either. They'll be their usual selves, have a great spell somewhere in the season and then just everything falls to pieces again with airplanes with "Wenger out"-banners flying over the Emirates. Sanchez isn't fit to start the season, Özil is in the last year of his contract, they're not very good defensively and it remains to be seen how Lacazette does in the PL. I'm not convinced from what I've seen from him so far.
I think Mourinho will have a great shot at the "most boring team of the season"-trophy. Everything is setup to just sit back and play on the counter-attack. You can't play dominant football with Lukaku as a striker. They had a crazy amount of draws last season, I'm predicting we'll be seeing quite a few of them again this season.
My prediction (might change of course, there are still 3 weeks to go in the transfer window):
1. Manchester City
2. Liverpool (if we manage to get Van Dijk)
