I agree with you to an extent. However, we can’t cull that many players, and therefore can’t make that amount of saving. That’s 9 players you’ve identified - the money saved would bring in 1 maybe 2 decent players. I would be happy to get rid of half of them for peanuts this summer, and the other half next year.
Centre back is an obvious place where we need to get rid of players, and I would be happy to get rid of Rojo, Jones, Bailly and belatedly Smalling. Smalling is the only one we could get a fee for.
