Vertonghen deflected long-range strike, his first goal since October 2013, ensured Spurs would coast home from the 71st minute.
Pochettino made a number of changes for the game against Wimbledon at Wembley, but still put out a very strong team against the League One side, with Vertonghen, Mousa Dembele and Harry Kane all featuring.
After making it clear he thinks the club should be fighting for the top four, and also making sure they do well in Europe, it was claimed he does not think winning one of the domestic cups is good enough for the club, yet he says that could not be further from the truth.
"That is why it is so important how you care for your players - it is why you need to anticipate things".
"I think Harry is this type of a player who can stay all his career at Tottenham because he loves Tottenham". It is today, the present. It's so important to work on the human side, to try to create a project where the players feel comfortable and happy to be with you.
"Only a few players can stay at a club their whole career and Kane can be someone like that".
Kane signed a new five-and-a-half-year contract in 2016 worth more than £100,000 a week but his wages are still modest in comparison to the world's leading players.
"Liverpool is historically one of the best clubs in the world, but when a player like Coutinho wants to leave, it is hard". Liverpool wanted to keep [him] but it was hard to keep him - and look what happened with Cristiano Ronaldo and Man United and [Zinedine] Zidane at Juventus, [Luis] Figo in Barcelona.
