Assuming Anel, Souza and Hamer leave, picked 3 free transfers and 3 permanent paid transfers from L1 who are good investments and could step up.
Free: Dunne, Darling and Tyrys Dolan (who I think is out of contract)
Dunne and Darling for cheap is half of the defence rebuilt, and Dolan would be a good fit for our right hand side.
Permanent signings: Sam Tickle (Wigan), Davis Keillor-Dunn (Barnsley), Luca Connell (Barnsley).
Sam Tickle, good keeper who might be worth investing in, fee shouldn't be too much as Wigan's ongoing financial issues might make them desperate to sell.
Davis Keillor-Dunn, I've seen quite a few highlights for Barnsley this season and this bloke looks top class, one of the best players in L1, seems to play anywhere across their front line and might be the best Hamer replacement I can think of.
Luca Connell, been a fan of his for years, think he'd be a good fit for us.
Also heard a few rumours (from Barnsley fans) that their owners might be looking to sell a few of their players if they don't go up this season, and they aren't anywhere close to the playoffs this season.
If Barnsley are going to sell a few players in the summer, I hope we go in for these 2, especially Keillor-Dunn.
