Chelsea's choice of kit against Middlesbrough was the main talking point for Tuesday night's Carabao Cup semi-final.
Mauricio Pochettino's side were drawn against Middlesbrough after beating Newcastle on penalties in the quarter-final.
The first leg took place at Middlesbrough's home ground, the Riverside Stadium.

Chelsea wore their away kit for the game but fans were left baffled as that was also blue and not too far away from their home strip.
There was no kit clash given Middlesbrough play in red and their away kit being a darker shade of blue led to plenty of reaction online.
One said: "I still find it hilarious Chelsea’s away kit is blue."

A second commented: "How is this an away kit. Literally would pass as a Chelsea home kit.
A third asked: "Why is Chelsea’s kit different? I thought I was going mad.This makes absolutely no sense."
A fourth concurred: "What is the point of this Chelsea kit? It’s exactly the same colour as their home kit.
A fifth user added: "Can’t help but question why Chelsea, who play in blue, have an away kit that is also entirely blue."

A final fan stated: "Two games for this pointless Chelsea change kit, two needless kit clashes created. Excellent work."
Chelsea's away kit was released in late August and is said to be inspired by the late 1990s with its diamond pattern.
It was described as the "perfect look for Chelsea away" but even upon its release fans feared they wouldn't be seeing much of it due to its similarities to the home.

Chelsea's third kit is a mint green colour and has been worn more regularly than the away.
Their home shirt for next season has been leaked online and is set to see one of the most bold designs from manufacturers Nike.
The shirt will be blue and white with a wave design across the front and red lines around the collar.
