I would look to move these guys on as a priority.
Son 200k - Should go to MLS and retire gracefully. He cant beat a man anymore. Hes not PL quality.
Romero 170k - Top player, but barely plays 25 games a season. Injury Prone.
Maddison 170k - Doesnt do it often enough. Slightly injury prone
Werner 170k - No justification needed
Richarlison 160k - Injury Prone, inconsisent. Good on his day, but not worth the money.
Reguillon 80k - Out of contract
Manor Solomon 60k - Not really good enough
Alejo Veliz - 40k - Why did we buy him?
