Kane has been down twice holding his ankles and you can hear the worry from the crowd. Fans of both Tottenham and England need him to stay fit.

Son Heung-min has Frankfurt on toast here. He's tackled by Makoto Hasebe and both players go down. The referee calls the physios on.

Hasebe would be getting a yellow card there if he hadn't been shown one a couple of minutes ago.

Mehdi Taremi has scored two penalties inside 10 minutes of each other as Porto now lead 3-0 away at Bayer Leverkusen and that is going to catapult Porto up to second in Group B.

Porto play at leaders Club Bruges next time out after the Belgian side secured a last-16 place earlier today.

Viktoria Plzen have a goal back through Adam Vikanova against Bayern Munich, although the Germans lead 4-1 and are heading into the last 16.

Tuta has been sent off but it wasn't clear at the time. He's picked up a second yellow card for a foul on Son. The referee seems to have booked two players in one go during that stoppage and Tuta is shown the red. He's waved down the tunnel by the home fans as he takes a slow walk off the pitch.

Son Heung-min had an effort saved by Kevin Trapp just after all that mayhem.

Not sure what was going on there. Tuta pulled Son Heung-min's shirt and was shown the yellow card. Spurs players pointed out he'd already been booked and after about 45 seconds, the referee showed him the red card.

Makoto Hasebe was booked too.

Eintracht Frankfurt are down to 10 men with pretty much the same move as three minutes ago.

Harry Kane finds Son Heung-min with an impossible pass and Tuta fouls Son. He's booked and - after a delay while the referee works out what's going on - is sent off.

Not sure if this is a shot or cross from Son Heung-min from this left-wing free-kick but it's punched away by Kevin Trapp.

Harry Kane plays a volleyed pass over the top in midfield that somehow finds Son Heung-min. Telepathy.

Son cuts inside Tuta, who brings him down and gets booked.

Roberto Firmino has his second goal of the game and Liverpool lead Rangers 2-1 now.

Follow that here.

Inter Milan have equalised at the Nou Camp, thanks to a goal from Nicolo Barella after a mistake from Barca defender Gerard Pique.

Slick football from Spurs. A last-ditch tackle stops Son Heung-min having a free shot 10 yards out.

Soooooooo close for Spurs. Richarlison shows great determination down the right to beat a defender and plays a good low ball to the back post. Ryan Sessegnon is six yards out but tackled as he shoots and Kevin Trapp makes a good save.

Good play by Cristian Romero and Emerson Royal to break up Frankfurt's first attack of the half. Spurs are back on the attack now but Son Heung-min can't quite keep the ball in.

Bright start for Spurs, this. Not much going on for Frankfurt.

Spurs are straight on the attack but Son Heung-min can't do something with the ball 20 yards out.

The second half begins. Spurs fans will be hoping for more of the same.

This would be a ninth home win in a row for Spurs in all competitions.

This is just the second time Tottenham have scored three or more goals in the first half of a Champions League game.

The other occasion was against Red Star Belgrade in October 2019 with the same scoring combo as today - Son Heung-min scoring twice and Harry Kane netting the other.
