Succession is something the club has to get better at. Objectively Dom is likely here for another year (any more than that you could actually suggests is poor business in relation to his value). This year you get in a 15 million range prospect with a year of development, brought in and hopefully be an in-house replacement or one of a committee, oppose to then reinvesting 2/3rds of Dom's return at the most premium position that would have to have an immediate impact.
DCL is logically going to be gone a year from now. Not leveraging that fact with the ability to bring in a bit of a rawer/cheaper prospect, while also factoring the injury risk and drop in goals in our squad I think would be foolish.
