None of us can be sure than Hunemaier, (or Goldson for that matter), are up to playing in the Premier League anyway. It will be a totally new experience to both of them.
Thinking about it, and looking ahead, possibly we do, a centre back in case we recieve an offer we can't refuse for Lewis Dunk, and as for midfield, I can't see Steve Sidwell being offered a new contract. Kayal has yet to prove himself in the Premier League too.
