As has already been said we are not going to keep him forever but the more I think about it maybe letting him go to the olympics was part of an agreement with him to stay for one more year.
In twelve months time everybody will know what the new normal for football will be. Crowds will be back... hopefully permanently and clubs will have their finances back to a point where they at least understand what is happening.
This summer the sale of Richarlison would probably mean Real think he is far too expensive and we think he is far too cheap.... in twelve months time a new transfer market level may have evolved.
Benitez would get to keep him for a season and we would have the promise of substantial funds from the sale in twelve months time.
Richarlison is still so young that twelve months more won't make that big a difference.
The only caveat may be that CA cannot afford to wait twelve months.
If Real have another season without winning a major trophy then Ancelotti will be sacked so he has to get his team in place quickly, but then will Real want or be able to afford a fee of 80m odd ?
