Vertonghen headed Spurs into an early lead - an advantage that was restored after 18 minutes by Dele Alli following Joselu's equaliser for the hosts.
At St James Park yesterday, despite the ongoing shenanigans behind the scenes, the Newcastle United support got behind their team. The Magpies quickly fought back thanks to a goal from Joselu, before a Dele Alli header won the points for the visitors.
For only the second time in Premier League history, Newcastle haven't named a debutant in their starting XI on the opening day.
Head coach Mauricio Pochettino will be happy given the fact that most of his players were coming on the back of little to no training at all.
Spurs will look to build on today's win when they take on Fulham at Wembley next week.
In the meantime, here are the Spurs players rated in their narrow win over Newcastle. Tottenham looked like the more dominant side for most of the first half as they maintained more possession, created more scoring chances and found the back of the net on two occasions.
Serge Aurier (6/10): Struggled at times, defensively, often making rough tackles, which eventually earned him a yellow card. "Sometimes we were a bit lucky but it was a very good start for us". A powerful strike from Mohamed Diame early in the second half rocked the post and went out of play.
The Brazilian was the most important signing made by Newcastle during the summer. Definitely the man of the match!
Ben Davies (6.5/10): An average showing from the former Swansea star who remained resolute to prevent the likes of Matt Ritchie and DeAndre Yedlin from bombarding down the left flank.
"Eric Dier was so exhausted". He managed only four goals in all of last season.
MF Lucas Moura, 6 - After a wonderful preseason, much was expected. He said: "It was a scrappy game". The Brazilian completed six dribbles and that created a lot of space for Newcastle to attack.
Spurs had nine players in Russian Federation until the final weekend and they only returned to training on Monday, with the likes of Harry Kane, Dele Alli, Jan Vertonghen and Hugo Lloris having differing levels of fitness.
They perhaps lacked a central focal point in midfield until Mousa Dembele was summoned from the bench with around 25 minutes to play and Eric Dier still remains an awkward fit in that position from which Pochettino wants his team to get going.
