Sorensen, who has been linked with Turkish giants Galatasaray and Middlesbrough this summer, will get the chance to win a contract at Stoke if he impresses.

Whether Boro's interest is concrete remains to be seen because boss Gareth Southgate has claimed on numerous occasions that he is happy to let Ross Turnbull and Brad Jones fight for the number one jersey at the Riverside.
