Graham Potter has received death threats aimed towards his children following a poor run of form at Chelsea.
The Blues have won just two of their past 15 games in all competitions. They sit 10th in the Premier League table, 11 points adrift of the top four, ahead of their crucial clash with Tottenham on Sunday afternoon.
Potter has been under mounting pressure, with his side booed off the pitch by their own fans following a dire 1-0 defeat by bottom side Southampton last weekend. The former Brighton boss retains the support of the Chelsea hierarchy, but he says the past few weeks have been particularly tough.
