Perhaps we could include Aguero in the Mbappe deal: Say, £90 million plus Aguero? That way they get a fantastic replacement for Mbappe and we don't sell to a team we don't want to sell to.
They won't want Kun's wages.
Most likely for me, if we are in for both Mbappe and Alexis, is Aguero to Real and Benzema to Arsenal. Monaco to find replacements from smaller European or South American leagues, as seems to be their MO.
