Newcastle United could choose to sell a "dangerous" player in a surprise decision this summer, according to an update from journalist Martijn Krabbendam. The Magpies are about to embark on a busy summer in the transfer market, with new signings expected to arrive and current players potentially moving on to new challenges. Eddie Howe could decide that he needs a new goalkeeper at the end of the season, with Valencia stopper Giorgi Mamardashvili emerging as a possible option to bring in between the sticks.
