Hopefully goes out on loan next season, ideally to a League One team who pass it out from the back.
Szczęsny went on loan to Brentford when they were in League One and said it was a great experience. He said it was a great, but hard, introduction to first team football playing against big, physical players. Gunn would really get tested in crosses in that league. The English lower leagues are great experience for young goalkeepers and defenders, not so much for the more technical attacking players as it's very physical.
It would be a good experience for Gunn, he'd certainly learn a lot.
