Birmingham City know they must play Jack Butland next season in order to keep him.

The Mirror says their goalkeeping coach Dave Watson, who has coached Manchester City goalkeeper Joe Hart, believes the 19-year-old is the potentially most best of the three.

Blues know they must give Butland - currently gaining first-team experience on loan at League Two promotion chasers Cheltenham - a chance next season, whatever division they are in, to keep the talented shot-stopper, amid interest from Arsenal.
