Chelsea fans sing to Pochettino 'You don't know what you're doing' after one decision

The Stamford Bridge crowd turned on Mauricio Pochettino in the second half of Chelsea's 4-2 win over Leicester in the FA Cup quarter-final.

The lowest point came after the head coach decided to replace Mykhailo Mudryk with Carney Chukwuemeka.

Fans, however, had been urging him to take Raheem Sterling off after a poor performance.

So, when Mudryk's number emerged on the fourth official's board, boos were swiftly followed by the chant 'You don't know what you're doing'.

Sterling did not last on the pitch for much longer, leaving it a few minutes later for Noni Madueke.

Both subs worked out well in the end, though, with Chukwuemeka and Madueke scoring in the final minutes to take Chelsea to Wembley.
