Mauricio Pellegrino is the latest Premier League manager to face the sack after a chain of disappointing results. It is recorded that the average Premier League manager does not last longer than 1 year and 3 months. The Southampton manager has been let go after a run of one win in the last 17 games. He confirmed on Saturday that his players looked like they had given up when they lost 3-0 to newly promoted Newcastle. The club have now decided that new management is the solution for the team that has been playing some entertaining football in the past few years. Assistant manager Carlos Compagnucci and first-team coach Xavier Tamarit have also parted company with the club. Do you think that this culture of sacking managers in the Premier League is the only way to guarantee success?
