Pep Guardiola conceded he is surprised to have Leroy Sane potentially among his attacking options for Tuesday's Champions League tie at Basel.
City return to the last-16 stage of Europe's top competition having established a dominant 16-point lead at the top of the Premier League, although injury concerns have mounted for Guardiola over recent weeks.
The City boss reported Sane would be absent for up to seven weeks with ankle ligament damage sustained in the 2-0 FA Cup fourth-round win at Cardiff City two weeks ago.
But the Germany winger stepped up his recovery last week, took part in City's pre-match training session on Tuesday and flew with his team-mates to Switzerland.
