My initial assumption was that Manchester United attempt at signing Casemiro would not materialize. It looks like Casemiro is already very close to Old Trafford as Manchester United proposal made him tempted to join.

Fabrizio Romano announced via Twitter that Casemiro would face Carlo Ancelotti to discuss his future.
Real Madrid seems to be releasing Casemiro like they released Varane who is considered to have given the best for Real Madrid.
Regarding the price, Manchester United offered 60 million.
