Claudius They also have Nunes who cost more than than all but 4 of our players.
Not sure if I read you correctly, your initial point was that only at Arsenal we play most of our expensive signings and don't discard them. So shouldn't you be comparing City starters with their bench players rather than compare their signing cost with our signings? Like what Burns pointed out, they generally play all their expensive signings.
Grealish was injured and also had a suspension by the way. He is definitely one of their used players and not wasted on the bench type.
