Give him the salary, he deserves it...
Bernardo gone, Kovacic probably gone, Marmoush as well, Ake plus
That's 1m of week salary budget
at least 20% of that will be enough to make Rodri stay
Apart from Rodri contract, we will need one CDM like Anderson and one RWB or RW
That's it
But if Rodri gone, we will need to pay additional 80-100m to find another top class midfielder as only Anderson won't be enough
Rodri, Nico G, Anderson and Foden / Reijnders / Matheus / Oreilly to cover those zones sometimes, is very good selection
