Hello and welcome to Eurosport's live digital coverage of Serbia vs Portugal in World Cup qualifying! Portugal began their campaign with a 1-0 win over Azerbaijan on Wednesday and now face a Serbia side who beat Republic of Ireland 3-2 on the same night. Kick-off is at 7:45pm UK time with team news coming right up!

Serbia fought back from two goals down to draw 2-2 with Portugal in a high-octane World Cup Qualifier here in Belgrade. But it ends in the most controversial of circumstances!

OFF THE LINE! Unbelievable! Serbia clear the ball off the line!! First Ronaldo's finish is slid off by Mitrovic! Ronaldo is then booked for his protests! There is no VAR here and it looked very, very close. Did it go over the line? It must have been centimetres! Ronaldo is fuming and throws his armband down in disgust and storms down the tunnel.

RED CARD! Late drama here as Milenkovic is shown a straight red for a crunching challenge on Danilo. It was a poor sliding challenge but a straight red seems harsh. Serbia down to 10!

SUB! Palhinha is on for Fernandes.

THREE minutes of added time.

Portugal look to be out of ideas while Serbia are happy to soak it up. Will someone find a last-gasp winner? It's hard to see it right now.

SUB! It's a change of Serbia strikers. Mitrovic comes off for Jovic.

YELLOW! For Mitrovic for bundling Fernandes over. SUB! Portugal are bringing on some fresh firepower. Felix is on for Jota.

Portugal have had a lot of the ball in these last few minutes and they look the more likely to score a winner. Serbia are very compact now.

Fernandes attempts an audacious shot from range but Pavlovic bravely blocks the powerful strike. SUB! Tadic comes off, handing the captain's armband to Mitrovic, for Djuricic.

Milenkovic gives away a poor foul on Jota to hand Portugal a good chance to swing the ball into the box. The Liverpool forward was not going anywhere there. The free-kick is taken quickly but the ball into the area is cleared away.

Ronaldo has not got his shooting boots on tonight. He fires an effort off his right boot outside the box, but it flies well wide.

OFFSIDE! Ronaldo will be relieved to see the flag go up. Fernandes found him completely unmarked around three-yards out, but he mistimed his run and got the ball caught in his legs.

SUBS! It's a double change for Portugal. Cancelo and Oliveira come off for Mendes and Sanches.

Mitrovic wins Serbia their fourth corner off Cedric. The Fulham striker has looked a different man in this second half. He is up for this! The ball swung in finds Milenkovic but he cannot make clean contact.

Portugal have regained some composure following a flurry of Serbia attacks. Serbia are still looking very threatening on the counter-attack and Dias fouls Tadic. The Ajax man has been causing plenty of problems in this second half.

Radonjic's fierce strike is smashed straight at Lopes who clears. There's roars from the Serbia bench for handball but the referee is not having any of it.

Serbia want another one! Mitrovic sprints into the area but he is tackled by Dias before Fonte dives into deny Tadic. The following corner comes to nothing.

GOAL! Serbia equalise!! It's a rapid, clinical counter-attack that ultimately does it. Radonjic plays an incisive pass into the path of Kostic who calmly slots the ball past Lopes! Serbia are back in this! Portugal are stunned!

Ronaldo has a go but the wall does its job and Portugal have a corner. Fernandes' corner is cleared at the near post by Mitrovic.
