3 Things We Learned From Chelsea's 3-2 Win Over Derby County in the Carabou Cup

Chelsea held on to their lead to win 3-2 against Derby County in the round of 16 of the Carabao Cup. They will now face Bournemouth in the quarter-final. Derby had themselves to blame for the loss, having gifted two goals through their own defenders in the first half. 

With the Blues resting many regulars and utilising their squad, Here are three things we learned in Chelsea's 3-2 win over Derby County.

3. Derby's own goals

Chelsea will thank Derby's two central defenders for gifting them the two opening goals. Both  Fikayo Tomori, a Chelsea loanee, and Richard Keogh saw their attempts to clear Zappacosta's cross go into the back of their own net. The Blues finally did score on their own, when Cesc Fabregas fired in the third goal, to give them the lead once again.

2. Chelsea had a scare

Chelsea were not exactly comfortable winners on the night, and that is something manager Maurizio Sarri will need to work on if he has ambitions of challenging for the league title. The Derby forwards came close to equalising a number of times, but were thwarted by the goal post or a last ditch tackle. On another night, Derby would probably have taken the game to the penalty shootout. 

1. Chelsea's loanees shine

Although Tomori did score an own goal against his parent club, he did have a good night overall, and did not let the unfortunate incident at the start of the game to demoralise him. Another Chelsea loanee who had a good game was Mason Mount. He was a thorn in Chelsea's side, and even provided the assist for Martyn Waghorn's equaliser. If they continue their development, they should soon be knocking on the doors of the first team.
