We started well in front of a record* 85,011 attendance - Heung-Min Son was denied on the line by Kamil Glik after just eight minutes - but two poor goals conceded after 15 and 31 minutes left us with a mountain to climb at 2-0 down against the unbeaten Ligue 1 leaders.
Toby Alderweireld replied on the stroke of half-time, Dele Alli went close within a minute and chances came and went in the second half with Harry Kane’s late strike straight at Danijel Subasic the last clear opportunity to rescue a point.
Below: Mauricio speaks to Spurs TV at Wembley
“I think I’d agree with everyone watching the game, we feel very disappointed,” said Mauricio.
“We started very well and created a few chances to score but then the way we conceded the goals disappointed me a lot because in the Champions League, you cannot concede the goals how we conceded.
“We were better than Monaco and you can see that in all the stats but in football, you pay when you make mistakes and we paid today because we conceded two goals from two shots on target. At the same time, I think we created chances but we weren’t clinical enough.”
Mauricio on the goals conceded
“We need look at ourselves and be more critical because it was our mistakes how we conceded the goals. It was easy for Monaco to score.”
On lessons to be learned
“We need to learn and we need to improve. It’s a shame because today was a fantastic day to share with our fans, to give a victory and a good performance, so we feel disappointed because the result wasn’t how we expected.”
Still all to play for
“It’s true we still have an opportunity. This was the first game, but we need to learn a lot and quickly. We need to play with more passion, more hunger, we cannot concede and we need to be more aggressive, it’s our responsibility to improve a lot.”
*The 85,011 crowd at Wembley sets a new Club home attendance record, the highest for an English home club in the Champions League and a new all-time record for an English home attendance, toppling City’s 84.467 at Maine Road in 1934.
