I have already explained, it’s based on three things:1) He just signed new contract last summer, 2) having very good season, even better than last season means he will cost more than 70m as it was last summer price tag, 3) Aston Villa has very rich owner
1. Doesn’t necessarily mean much, except that Villa will receive a good fee (100m is a little more than “good”).
2. He’s a year older than last season, too. Villa have also gone a long way to stabilising their PL position, so their attitude towards letting him go could change.
3. If he decides he wants to leave, there’s really not a great deal that can be done. Taking the 70m or thereabouts would make sense.
IF he decides he wants to go, I think it could easily happen, even for slightly less than 70m. 60m could buy them 2 players of real quality, maybe even 3, 4 etc...
