Nathan Ake will make his first appearance in a Manchester City squad since before the international break on Tuesday night.
The former Bournemouth defender is part of the 23-man group aiming to secure top spot in their Champions League group. City have already qualified, but Pep Guardiola is determined that his players maintain their standard and has not left anyone at home to rest despite acknowledging the Premier League is a priority.
Sergio Aguero will remain in Manchester after feeling some discomfort in the knee that kept him sidelined for five months earlier this year. The Blues are not overly concerned by his absence but want the striker to feel right before returning rather than rushing back and risking another setback - as happened last month.
Tommy Doyle will also be in the matchday squad against Porto, having made his Champions League debut for the club last week in the win over Olympiacos. He is the only academy player present, however, as Guardiola turns to his senior players for the result needed to box off the group with a game to spare.
City are trying to build some momentum after a disjointed start to their campaign. Their Champions League results have been flawless but the team have been unable to transfer that form into the Premier League, only climbing into the top half of the table with a 5-0 win over Burnley at the weekend.
City squad: Ederson, Steffen, Carson, Walker, Cancelo, Dias, Stones, Ake, Laporte, Garcia, Mendy, Zinchenko, Gundogan, Rodri, Bernardo, Fernandinho, De Bruyne, Doyle, Mahrez, Foden, Torres, Sterling, Jesus
