Tottenham Hotspur 3-1 Real Madrid: 5 Talking Points as Spurs qualify for Round of 16

#2 Spurs' first goal was offside but it was always coming

Kieran Trippier was offside when he received the pass over the defence

Tottenham scored the opening goal in the 27th minute but there was a controversy over whether the goal should have stood. When Kieran Trippier made the run on the right side of the box, he was clearly a foot offside.

It is a tough call for a linesman to make as the pass was made 36 yards from goal while Trippier was in full sprint. But once he did receive the ball, Alli split the two centre-backs to put away the cross.

But the warning signs were clear. It wasn't the first cross of the night from Spurs. Trippier had already put in a lethal cross across goal that Spurs failed to put away while even Jan Vertonghen had managed to get up field and put one in from the opposite flank - only to be thwarted before an unmarked Harry Kane pounced on it.

Kieran Trippier was one of Spurs' best players

Pochettino had instructed his forwards to attack the large gap between the two Real centre-backs - Nacho and Sergio Ramos.

Whether it was Alli or Kane, the two made some potentially productive runs into the centre of the box and Trippier could have actually walked away with a hat-trick of assists if things had gone according to plan.
