Porto vs. Chelsea takes place tonight in the Champions League.
The game, which takes place at the Estadio do Dragao, is scheduled to kick off at 19:45 BST and airs live in the United Kingdom on BT Sport Europe/BT Sport Europe HD.
Chelsea manager Jose Mourinho will be looking for an immediate response after giving his side a mark of “minus one out of 10” for their first-half performance in the 2-2 draw against Newcastle in the Premier League on Saturday.
Chelsea came back from two goals down to earn a point against the Magpies, but Mourinho was livid with his players’ display in the first 45 minutes at St James’ Park.
“In the first half, from 0-10, we were minus one. It was that bad,” he said.
“We were so poor, so bad. At half-time I said I was sorry I only had three subs as I wanted to change six.”
Mourinho may make changes to his starting line-up against Porto as he tries to figure out what was behind their poor first-half showing against Newcastle.
“In the second half we played very well,” the Blues boss added.
“Ramires and Willian moved the game, they brought more intensity, were much more dynamic. Newcastle could not cope with it.
“I have to try to understand why they can play so bad in one half and so well in the other. We were bad in every aspect of the game in the first half.
“Too many poor individual performances and it was impossible to be a competitive team.”
