Erik ten Hag has warned Leeds United that sacking manager Jesse Marsch won't guarantee an upturn in results.
Leeds axed Marsch just two days before Wednesday's clash with Manchester United at Old Trafford following a dismal run of seven Premier League games without a win.
Some clubs have enjoyed a 'bounce' when changing manager this season. Unai Emery beat United in his first game in charge of Aston Villa in November; and Everton's Sean Dyche was the latest to get off to a winning start.
But Southampton, Bournemouth and Wolves are still battling for survival with Leeds and Everton towards the foot of the table, and Ten Hag insists that wielding the axe doesn't always get results.
