Tottenham boss Mauricio Pochettino conceded his side were lucky to survive a huge upset after a late rally saw them scrape past League Two Wycombe Wanderers in the FA Cup Fourth Round.

Spurs ran out 4-3 winners at White Hart Lane, thanks to a deflected effort in the 96th minute by Heung-Min Son, but were fortunate to avoid an embarrassment.

A giant killing looked on the cards after the home side had gone in at the break 2-0 down, before clawing the game level through goals from Heung-Min Son and Vincent Janssen after an hour.

Wycombe then regained the lead with just seven minutes of normal time to play, but an 86th minute strike from Dele Alli and Son’s last-gasp winner booked Tottenham’s place in the next round.

Pochettino said he had congratulated Wycombe manager Gareth Ainsworth after the final whistle and admitted the League Two minnows had outperformed his side for much of the game.

He said: “I told him well done, well played and that this is football, sometimes you need to be a little bit lucky to win like us, we scored in the last seconds.

“But I congratulated him because I think today his team played very well.

“Full credit to Wycombe because from the first moment they played well and they found a way to create chances.

“Of course it is true that they played better than us and in the first half, they beat us 2-0 and that was because they played better than us, it was not lucky.

“Maybe that is the beauty of the FA Cup that two different levels of team display a similar level of quality.”

“It was difficult for me from day one when I arrived in England to talk about the magic of the FA Cup but now I realise.

“It is a special competition, I think it is the most special competition in the world because you cannot replicate it in Spain or France or Italy.

“All the small sides coming from League Two are exciting, but they think they can beat us here and that is the important thing.”

With their name now in the hat for the FA Cup Fifth Round draw, Spurs will return to Premier League action on Tuesday night, when they travel to struggling Sunderland.
