against their compatriots and reigning English champions Manchester City, with two legs scheduled within 11 days of a Premier League fixture between the clubs. Tottenham hosted the first leg, the first European tie at the newly-completed Tottenham Hotspur Stadium, and won 1–0 thanks to a goal scored by Son Heung-min in the 78th minute, following an earlier penalty from City's Sergio Agüero in the first half that was saved by Hugo Lloris. Manchester City took an early 3–2 lead within 21 minutes to open the second leg, including two goals apiece for Son and City's Raheem Sterling and an additional goal scored by Bernardo Silva. Agüero's goal in the 59th minute gave Manchester City a 4–3 lead on aggregate in the series, but Fernando Llorente scored in the 73rd minute to tie the series once again and give Tottenham an advantage on away goals. Sterling scored a fifth goal for City in the third minute of stoppage time, but it was ruled out by the video assistant referee for an offside during the buildup to the goal, giving Tottenham a victory on away goals to send them to their first European Cup semi-final since 1962. In the semi-finals, Tottenham faced Dutch club Ajax, who had won the European Cup four times. A resurgent Ajax had entered the competition through the qualifying rounds with a young squad and went on to eliminate reigning holders Real Madrid in the round of 16 and Juventus in the quarter-finals. Spurs, missing forwards Harry Kane and Son Heung-min, among others, to injuries, lost 1–0 in the first leg at home, Ajax's lone goal coming in the 15th minute from Donny van de Beek. Ajax began the second leg at their Johan Cruyff Arena with goals from Matthijs de Ligt and Hakim Ziyech to extend their aggregate lead to 3–0 at half-time. Tottenham manager Mauricio Pochettino substituted defensive midfielder Victor Wanyama for striker Fernando Llorente at half-time, and his strike partner, Lucas Moura, scored the team's first goal of the semi-final in the 55th minute. Moura then scored a second goal five minutes later, his tight footwork helping him beat several Ajax players after an initial save by goalkeeper André Onana. After Tottenham failed to convert several chances to level the tie, the match entered five minutes of stoppage time. As the clock passed the five-minute mark, Moura completed his hat-trick with a first-time shot from
