Porto will welcome two key players back from suspension for the second leg of their Champions League quarter-final clash with Chelsea on Tuesday.
Trailing 2-0 from the first leg, Sergio Conceicao is boosted by the returns of Mehdi Taremi and Sergio Oliveira, and both goal-getters should be reinstated to the starting lineup in Seville.
Toni Martinez once again found the back of the net in the league at the weekend, but Taremi's return means that the Spaniard is likely to drop down to the bench, while Moussa Marega is sure to displace Evanilson in Conceicao's forward pairing.
Oliveira and his 19 goals will be welcomed back to the midfield with open arms - assuming that his recent muscular problem is nothing to worry about - so Liverpool loanee Marko Grujic may be the unfortunate one to drop out as Mateus Uribe keeps his spot.
Luis Diaz had to make do with a substitute appearance at the weekend and may be forced to accept the same fate in Seville, even though an error by Jesus Corona led to Chelsea's second goal on the night.
Chancel Mbemba was rested at the weekend but is expected to return over Diogo Leite alongside the veteran Pepe, and backup goalkeeper Diogo Costa has tested positive for coronavirus, but Agustin Marchesin's spot in between the sticks was never in any danger.
Porto possible starting lineup: Marchesin; Manafa, Mbemba, Pepe, Sanusi; Corona, Uribe, Oliveira, Otavio; Marega, Taremi
