Manchester City manager Pep Guardiola has acknowledged that Sergio Aguero is “Almost fit” after a muscle problem and he will travel with the squad.
Oleksandr Zinchenko is out with a hamstring problem, so Danilo or Benjamin Mendy will start at left-back.
Brighton winger Solly March is a fitness doubt because of the tight calf that prompted his substitution at Chelsea in midweek.
They also carry a threat from set pieces, with Shane Duffy and Lewis Dunk always happy to be brave in a congested penalty area.
Brighton will raise their game at Wembley, but they are playing a Manchester City side who have found their groove.
The five-time FA Cup winners are on a run of 21 wins in 22 matches, including the penalty shootout victory in the Carabao Cup final.
Pep Guardiola’s side have scored an unrivalled 19 FA Cup goals this season.

- Brighton have only won one of their last 11 matches with Man City in all competitions (D3 L7), a 2-1 victory back in April 1989 in a second-tier clash.
- Manchester City have progressed from 10 of their previous 13 FA Cup semi-final appearances, including eight of the last nine. The Citizens have never lost back-to-back semi-finals in the competition.
- Brighton are winless in their four previous matches at Wembley Stadium (D1 L3); should they fail to win, they will become just the fifth different side to win on none of their first five visits to the stadium in all competitions (Brentford, Leicester City, Middlesbrough and Shrewsbury Town).
- Manchester City have scored more FA Cup goals in 2018-19 than any other side (19). Indeed, they are looking to become the first side to score at least 20 times within a single campaign since Chelsea back in 2011-12 (20), and the first time the club has done so since 1980-81 (20).
