Dan Burn had only been away from Newcastle United's training ground for a few months. It has been another turbulent summer on Tyneside following the departures of manager Eddie Howe and influential figures Bruno Guimaraes, Sandro Tonali and Anthony Gordon. Head coach Matthias Jaissle has brought half a dozen members of staff with him, while Burn has also been getting to know a handful of new team-mates in Lukas Hornicek, Ewen Jaouen, Aladji Bamba, Sean Steur and Bazoumana Toure.
