Arsenal v Porto LIVE: Champions League result and final score as Gunners win penalty shootout

60 min: An hour gone and we’re all square on aggregate. Arsenal will be happy enough with how this has gone so far tonight, and they are certainly the favourites now. But Porto continue to carry a threat when they come forwards and they are defending doggedly.

58 min: Rice bends in yet another corner, almost all of which have been fizzed under the crossbar to test Costa, who Arsenal’s set-piece coach clearly doesn’t rate. This is another like that but Costa and his defence have dealt with the challenge so far, and the keeper punches this delivery clear.

55 min: Arsenal have a corner. Rice whips it in from the left and it’s well cleared by Otavio. Rice tries again and this time Pepe heads away. A moment later Havertz cross from the right but Rice’s shot is blocked.

Good pressure, this, by Arsenal, matched by Porto’s defending.

53 min: Francisco Conceicao hacks through the back of Trossard near the halfway line and the Emirates is furious. I’m not sure how that isn’t a booking, but it isn’t.

50 min: This time Conceicao is pickpocketed by Kiwior, good defending. Arsenal yet to get into their stride in this half.

47 min: A nice dribble by Francisco Conceicao, who jinks in from the right wing and into the box. His cross bounces up into the air off an Arsenal defender and Evanilson can’t resist trying a bicycle kick, which flies off target.

Martin Odegaard gets the second half going with a pass back to goalkeeper David Raya, who launches the ball downfield.

In the other game tonight, Napoli pulled a goal back after going 2-0 down and are still in the tie.

Leandro Trossard might not have been in the team tonight had Gabriel Martinelli been fit, but he is and he’s taken his opportunity with a piercing finish.

Clement Turpin blows his whistle and that’s half-time. Trossard’s goal gives Arsenal a deserved edge on the night, and it’s all square on aggregate.
