Pep Guardiola is on the cusp of immortality. The Spaniard is already revered as one of the greatest managers of all time, but he will have no equal if he brings the Champions League back to Manchester City.

City have dominated English football under Guardiola over the last six seasons, but a maiden European title has so far proven elusive. After several years of underachieving, they finally reached the final in 2020-21, only to be beaten by English rivals Chelsea, and suffered a heartbreaking defeat to Real Madrid in last season's semi-finals.

Guardiola's men exacted revenge over Real at the same stage this time around, though, and are now the overwhelming favourites to lift the trophy in Istanbul. Coppa Italia winners Inter are the only team left standing in their way, and no one is giving the Nerazzurri a chance against the Premier League champions.
