Jubilant Legia Warsaw fans stripped to the waist in the away end at Stamford Bridge on Thursday during a shock 2-1 win over Chelsea that laid bare the hosts' lack of intensity in the second leg of their Conference League tie.

Chelsea booked their place in the Conference League semi-finals after a 4-2 aggregate win over Legia Warsaw. Enzo Maresca's side suffered a 2-1 defeat at Stamford Bridge on Thursday night in the 2nd leg, which was received by boos at the full-time whistle by the Chelsea crowd.

Chelsea takes on Legia Warsaw on Thursday, April 17, at the Stamford Bridge in west London, with kickoff set for a 8 p.m. BST start local time in the UK. That makes it a 3 p.m. ET or 12 p.m. PT start in the US and Canada, and a 5 a.m. AEST kickoff in Australia on Friday morning.
