The Cristiano Ronaldo gesture that has everyone talking after Juventus defeat

Juventus' 23-year wait for a Champions League trophy continues after the Serie A club were beaten by Ajax in the quarter-finals on Tuesday.

The Italian giants, who last won the competition in 1996, saw their hopes of claiming a third European title ended as the Dutch side sealed a 2-1 away win to book a semi-final meeting with Tottenham Hotspur.

Cristiano Ronaldo's 28th-minute header appeared to put Massimiliano Allegri's side on course for the last four before goals from Donny van de Beek and Matthijs de Ligt sealed a famous win for the Eridivisie team.

Ronaldo, who netted a stunning hat-trick against Atletico Madrid in the previous round, was aiming to win the Champions League for the fourth season in a row following his summer arrival from Real Madrid .

The quarter-final exit also means that the five-time winner won't feature in the last four of the competition for the first time since the 2009/2010 campaign and didn't hide his disappointment after the match.
