Rob Draper had the choice to pick any players from the south teams, in any formation, with no limit on the number of players from each club. Here's how we split the clubs: South Arsenal, Aston Villa, Chelsea, Crystal Palace, Leicester City, QPR, Southampton, Swansea City, Spurs, West Brom, West Ham United North Burnley, Everton, Hull City, Liverpool, Manchester City, Manchester United, Newcastle United, Stoke City, Sunderland North vs South. It is perhaps the fiercest argument between the people of England.No place for Diego Costa or Olivier Giroud as Harry Kane leads the lineSouthampton and Chelsea - the Premier League's meanest defences - make up the entire back seven of our Southern XIEden Hazard and Alexis Sanchez will play with Santi Cazorla behind KaneWe'll test who is better with help from Football Manager
