(Video) Gary Cahill makes two errors and gifts Derby County an equaliser

• Derby County equalise against Chelsea at Stamford Bridge.
• Gary Cahill makes two errors in the build-up to the goal.
• WATCH: Fikayo Tomori own-goal gives Chelsea the lead

Derby County have equalised against Chelsea at Stamford Bridge, and Gary Cahill ought to hang his head in shame.

Maurizio Sarri put faith in the Englishman tonight – he must now be wondering why he bothered.

Cahill not only gave the ball away in the build-up to the goal, he then slipped and allowed Derby to fire past Willy Caballero.

Thankfully for him, another Derby own-goal has put Chelsea back ahead. He’ll be the most relieved man in West London right now…
