Hello and welcome to Eurosport's live digital coverage of Republic of Ireland vs Portugal in World Cup qualifying! Portugal will go top of Group A if they win tonight, while Ireland will be looking to continue their good recent form. Kick-off is at 7:45pm UK time with team news coming right up!

Portugal edge closer to qualifying for the 2022 World Cup after holding on for a 0-0 draw against Republic of Ireland at the Aviva Stadium. The result means Group A leaders Portugal will host Serbia on Sunday in a winner-takes-all clash, with both locked on 17 points at the summit, but will do so without Pepe who was sent off in the 82nd minute after picking up two yellow cards.

BIG CHANCE! Ronaldo goes for goal himself from a tight angle but he fires it straight at Bazunu!

Hourihane's dangerous cross into the box is booted clear. Moments later Doherty has the ball in the net by Fonte but Patricio was fouled by Keane.

FIVE minutes of added time. SUB! For Ireland, Will Keane comes on for Ogbene.

Ireland are getting numbers forward but they cannot break down this staunch Portugal defence. A point would keep Portugal ahead of Serbia on goal difference at the top of Group A heading into their crunch clash in Lisbon on Sunday.

Ireland are piling on the pressure as they look to make their man advantage count. Doherty fizzes in a shot which is blocked before McCLean's cross is cleared away.

SUB! Leao, who came on in the 56th minute, is off for Fonte.

RED CARD! PEPE IS SENT OFF! Portugal will be without the experienced defender for their winner-takes-all clash against Serbia on Sunday! His flailing arm catches Robinson in the face and is shown a second yellow.

SHOT! Ronaldo goes for goal from the edge of the box with a curling right-footed effort, but it's narrowly wide!

SUBS! McCLean is on for Stevens and Hourihane comes on for Hendrick.

CHANCE! Ogbene's cross finds Stevens who makes a late run into the box, but his first time shot off his right boot is over the bar!

SUBS! Portugal boss Fernando Santos is making some changes. Felix comes on for Silva and Fernandes, who has had a quiet game, is replaced by Sanches.

ANOTHER YELLOW! This time it's for Pepe for a handball as he blocked Egan's lofted pass. Cullen's free-kick into the box finds Duffy at the far post but he cannot get enough on it and the move breaks down.

YELLOW! Danilo wipes out Ogbene and he is given a yellow card for his troubles. It was a clear foul as he lunged into the Ireland forward.

JUST WIDE! The best chance of the match falls to Ronaldo! Silva's cross from the right finds Ronaldo at the far post, but his header into the ground bounces just wide of Bazunu's right post!!

There's a roar of appreciation from the home fans after Duffy, on his 50th cap, shepherds the ball out of play with Leao on his back.

SUB! Ireland make their first substitution. Idah comes on for McGrath.

Doherty's cross into the box is caught easily by Patricio.

This game has been far more even than perhaps most expected. It's not been a classic so far, but Ireland will feel they are right in this.

Ronaldo is adamant that Duffy handled it but VAR says it did not. SUBS! For Portugal, Leao and Moutinho come on for Guedes and Matheus.
