Lo Celso loops a ball over the top for Bergwijn, but Ampadu tackles him well at the edge of the area. That should be that.

Penalty goal scored by T. Werner for RB Leipzig!
GOAL! Leipzig lead 1-0, Werner from the spot! He steps up confidently and drills a right-footed effort hard into the bottom-left corner. Lloris guesses right but can't get a touch to it. Super penalty - and an away goal.
56'
B. Davies gets yellow.
Davies is booked for his foul on Laimer in the area, with the Leipzig man receiving some treatment from the medical staff.
54'
Spurs get the corner away but struggle to get the ball out of their own half on the counter. Leipzig immediately close down Moura and force a mistake.

52'

46'

20'
Lloris makes a save from Angelino and launches the ball out of his hands towards Moura, who profits from a defensive slip and almost finds himself through on goal. The bounce of the ball just keeps it out of this reach, and he fouls Klostermann at the edge of the area.

1'
We're off! Leipzig get the ball rolling.
The visitors get a half-chance inside the first 30 seconds, with Schick flashing a shot wide to the right from the edge of the area.
We're back underway for the second half, with Spurs getting the action going again.
Hello and welcome to our live coverage of this Champions League last 16 first leg, with Tottenham hosting RB Leipzig.
Jose Mourinho’s side might find themselves up against it on home soil tonight, with star forwards Harry Kane and Heung-min Son both out and Julian Nagelsmann’s Leipzig just a point off the top in Germany.
TOTTENHAM (4-2-3-1): Hugo Lloris; Ben Davies, Davinson Sanchez, Toby Alderweireld, Serge Aurier; Gedson Fernandes, Harry Winks; Steven Bergwijn, Dele Alli, Giovani Lo Celso; Lucas Moura.
SUBS: Jan Vertonghen, Erik Lamela, Eric Dier, Paulo Gazzaniga, Tanguy Ndombele, Oliver Skipp, Japhet Tanganga.
RB LEIPZIG (4-2-2-2): Peter Gulasci, Angelino, Lukas Klostermann, Marcel Halstenberg, Nordi Mukiele; Ethan Ampadu, Konrad Laimer; Christopher Nkunku, Marcel Sabitzer; Timo Werner, Patrik Schick.
SUBS: Amadou Hairara, Yussuf Poulsen, Emil Forsberg, Ademola Lookman, Hannes Wolf, Dani Olmo, Yvon Mvogo.
The teams are on their way out onto the pitch, and we’re just moments away from kickoff.
You have to think Spurs will need to change something if they're going to get anything from this game, though preventing an away goal would be a real bonus. They've had less than 35% possession so far in front of their own fans.
That's it from me tonight, I hope you've enjoyed following the action. Until the next time, goodbye!
Nagelsmann will be disappointed his side haven't killed the game off, but an away goal and a clean sheet isn't a bad return for the club's first-ever Champions League knockout tie. Spurs know as well as anyone that a first-leg deficit is never unassailable in the Champions League, but they've got a battle on their hands in Germany.
