For me, id move on Gomes and Gana for £10mil combined and target Adam Wharton (Blackburn) or Neil (Sunderland) or Hackney (Boro).
Have to continue building a young squad that improves and develops long term on low wages (overall).
The other option like you say, or a Kalvin Philips would be worthwhile on loan till season end if we could sell the first two.
10m for Hama and gomes ? Might as well sell dobin for 60m and the ash tray in the players lounge for 500k as long as we are talking fantasy
