Madrid is unlikely but PSG is possible. Its the perfect place for him to find his form again since its an easy league with a dominating team and everyone gets to score a lot of goals. He can rediscover his confidence there, get paid well, grow and then later on go to a more competitive place.
Its pretty much Guardiola's league title to lose for sure next season. City at their worst right now are near winners, with this material plus much better coach and mandate to sign whoever he wants prolly should make it a lock. I hope Conte wins it if he gets the gig, but best bet to stop Guardiola and City next season would be if Chelsea gotten Simeone prolly. Mourinho if he goes to Man U has huge mess to deal with, big ask.
Chelsea are a bigger mess. They need a new defense, a Hazard replacement, a Costa sub and the entire squad is mentally broken. The entire squad except Willian needs therapy.
Chelsea have quality core players and proper structure (same players that won title less then a year ago). Broken mentally but can be fixed, especially if the coach is motivating one like Conte. What they need the most is RB, extra CB for starting eleven and they are good. Won't have issues getting depth for attack and midfield.
Man U in comparison are huge mess, much more so then Chelsea. Lack true quality across the board and pretty much filled with mediocrity or players that don't have any experience winning together. It will take alot for them to bounce back from Ferguson Era fully.
