If Martinez goes, whoever replaces him will have to know how to play the way Leicester, Spurs, West Ham, Southampton and LFC. High energy, marathon runners, get the ball forward very quickly to speed merchants, with one maybe two players that can turn a game and have a striker that can finish. A new manager will have to assemble a defence that is like Leicester's or Spurs and make sure they are the same faces week in and week out. If they do not introduce such a style then they have no chance of top 4, never mind winning the league.
Leicester have 'raised the bar' and no manager next season can make any excuses for their failure to win the league.
