The narrative on here is that Romero lost concentration, the ball went under his foot for a throw, and Burnley scored from it.
I just watched the whole passage of play back on SpursPlay, and there is a LOT more that happened.
Ironically the Spurs commentator says "Spurs are well on top here" because we were really dominating.
The Burnley keeper whacked it upfield, we dealt with it fine and passed it back to Vic.
As usual Vic could have played a simple pass to Romero immediately, but he hesitates, looks upfield, considers his options, then fires it 10% too hard and 10% too inaccurate at Romero.
It wasn't awful (for Vic) but it is those fine margins, the 2 second hesitation, the marginally wrong pass, and also of course Romero should EASILY have controlled it.
There is a throw in but the idiot TV director decides to focus on Walker's gormless face and Vic wrestling with someone and back to Walker, so we don't really see why this happens, but Porro comes all the way across from right back area to left back area. That is very strange and makes no sense to me. We leave the right back area to be covered by Solanke Gallagher Danso and Spence... strange right?
Then we clear that throw and it is recycled and they play the ball to the same area, VdV tackles Walker and it is another throw.
That throw goes backwards, then comes out to Walker again who pings in a perfect cross.
During this whole time Porro is playing left back, seems quite odd to me, and planned, as there was time to revert back?
Anyway, the back post is still Solanke Gallagher Spence Danso marking 4 opponents. Danso goes with a runner, the other sort of mark 2 players but basically they just watch Tuanzebe run in and smash it home. Very poor from them.
