I agree with the diagnosis Uphill, but not so sure on the solution.
I still don't think a maverick will go down well with Glasner as he wants players to fit his system (Uche/Esse for example). JPM has proved that he can score goals, albeit he is (naturally) prone to bad performances here and there.
I think our issue is goals outside of JPM. Sarr gets a few, albeit was equally horrendous as everyone else yesterday. Nketiah only ever really has cameos and is usually a replacement for JPM, but Pino/Wharton/Kamada/Lerma/Hughes etc??? Not many if many goals there. I think of Munoz as our next biggest attacking threat, with Mitchell getting our goal yesterday. Our two full backs.
We need goals from midfield. Without them, we've got a very limited supply and goals win you games.
