On Wednesday night, Tottenham Hotspur sent a very clear message that they mean business in the Champions League.Mauricio Pochettino's team already proved that they can hold their own against elite opposition when they restricted Real Madrid to a 1-1 draw at the Bernabeu.At Wembley, though, the players took a step forward by sealing a 3-1 victory over Zinedine Zidane's side, which also sent the club into the last 16 of the competition.Dele Alli, who had missed the first three group games due to a UEFA ban, scored twice before Christian Eriksen wrapped it up.In the end, Cristiano Ronaldo's goal was solely a consolation for the Spanish giants, who have lost back-to-back games for the first time under Zidane since January.Osvaldo Ardiles, who is widely regarded as a Tottenham legend, delivered his verdict of the match on Twitter, and pointed out a key difference between the two clubs.

Spurs have two more group games to play before they take on the first knockout round of the competition.
