Pedro Porro and Djed Spence were involved in a very interesting incident in training this afternoon as Tottenham trained in front of their fans in Hong Kong.Tottenham are now in the Asian leg of their pre-season schedule, with Spurs set to take on Arsenal on Thursday at the Kai Tak Sports Park in Hong Kong, in what will be the first North London derby outside of UK soil.It will also be Thomas Frank’s first North London derby in charge, and one would expect it to be an emotionally charged fixture, even though it is a pre-season friendly.Ahead of the big match, it does not appear that the Tottenham Hotspur players are holding back in training – certainly not a certain Mr Djed Spence, anyway.Credit: @thefrederikkejensen / InstagramDjed Spence leaves Pedro Porro in a heap after crunching tacklePedro Porro and Spence might be competing for the right-back spot this season, and they are certainly not taking any prisoners in training.Tottenham had an open training session at the Kai Tak Sports Park in front of their fans, and it is certainly clear that intensity was high.A video shows Porro taking a touch, but before he could react, Spence came in with a hard challenge to win the ball, leaving the Spaniard on the floor rolling around in pain.Djed Spence taking no prisoners in Tottenham pre-season training 💀Pedro Porro on the receiving end! 😅 pic.twitter.com/kPSy6RB2X6— Hayters TV (@HaytersTV) July 29, 2025 Can Spence become a regular Tottenham starter under Thomas Frank?We have already seen during pre-season that Frank likes to build up using a back three, with one of the full-backs tucking in while the other goes high and wide.When Udogie has started, the Italian has been the player to hog the touchline while Porro tucks in. However, one doubts Spence can be used in the Porro role, with the Englishman likely to be used as the maurauding full-back when he plays.One would thus think that Spence is more likely to play with Ben Davies as the left-back, while Porro might come into the team when Udogie gets the nod to start as the left-back.Tottenham are reported to be in the market for a new left-back this summer, which means the situation may change before the start of the season.READ MORE: Thomas Frank hints at what kind of forward Tottenham may sign this summerThe post Video: Djed Spence leaves Pedro Porro rolling on floor after crunching tackle in Tottenham training appeared first on Spurs Web.
