Real Madrid will be compliant of FFP rules once their buying ends, they’ll sell their top players and balance their books. The rebuilding has began at Real Madrid and once these players understand each other they’ll be unstoppable, now all they need to do is to buy the final player Pogba. Manchester United are playing hardball with them but I expect Pogba will push for the transfer, and leave Manchester United for good.
Real is doing top job in this transfer window. As you said now they have to sell someone as well. I believe Bale is top of the sell list. Zidane clearly showed he doesn't see him as a part of the squad. Only problem could be his wages which are probably a bit on the high side for most clubs but it should be in Bale interest to move on as well. He is still young enough to revitalize his career.
Pogba is top player but with problematic character, shouldn't Eriksen be better signing for Real? He will give his best trough good times and bad and will not cause media problems in case he needs to sit out the match or gets a bad spell of form.
Jovic today, Hazard to be presented tomorrow, Mendy next week...Now we wait for the Pogba or Eriksen official announcement in the upcoming weeks, plus, maybe Mbappe towards the end of transfer window?
