Luke Graham says he has aspired to be like "fellow lefty" Andy Robertson and now they are international team-mates. The 22-year-old Stoke City centre-half was previously in the Scotland squad without playing but has been called up by new national head coach Sebastien Pocognoli, with Robertson retaining his place in the squad. Robertson has now captained his country at three major tournaments and joined Tottenham Hotspur this summer from Liverpool while Graham left Dundee for Stoke.
