Chelsea make the trip to Lisbon on Wednesday for the first leg of their Champions League quarter-final tie against Porto.
The Blues resumed action after the international break on Saturday, where they suffered an embarrassing 5-2 defeat to West Bromwich Albion.
They were down to 10 men after just 29 minutes on the clock, but the nature of defeat was a surprise, given their solid defensive record under Thomas Tuchel.
The loss ended a 15-match unbeaten run across all competitions, and the Blues will be aiming to make amends with a strong display against Porto.
