Hughes, Schlupp and Ward have signed on for another year. All valuable squad members.

Conjunctivitis.com - A site for sore eyes.

I would've liked to have seen Hughes offered 2 years, I think he's been good enough this season to warrant it.

Would support Clyne and Matthews for another year too, although on significantly reduced terms in Clyne's case.

Assuming the decision re Riedewald's release has been known for a while I'm surprised an opportunity wasn't given to use either Ozoh or Ahamada as substitutes in recent games instead of Riedewald.
Perhaps Riedewald was used for specific tactical purposes in the games where he was used, but part of me thinks it would have been an opportunity to give Ahamada or Ozoh some experience.
Not a criticism, just an observation.
