It's 2-2 going into the second leg, as Arsenal host Sporting with it all to play for in North London next Thursday.

It was a lively game of football to say the least in the first leg, as a goal from Saliba and a second half own goal from Morita wasn't enough to take a win back to the Emirates as Sporting put on a strong display at home.

FULL TIME: Sporting Lisbon 2-2 Arsenal

90+3 Late corner for Arsenal..2-2

90+2 Saka tries his signature move, cutting in from the right and taking aim to unleash a curler at goal. His late effort is saved. 2-2

90' Four minutes added on. 2-2

89' The game nears an end after a dramatic ninety minutes, both teams would love to take a lead to the Emirates, at this point you'd expect Arsenal to be happy to take a draw back home. 2-2

86' Arsenal are looking for a late winner in Lisbon building play from the midfield on the edge of the box. Vieira went down in the box with penalty claims waved away. 2-2

80' Proceedings have calmed slightly as the game ticks on, Thomas Partey always seems to add an element of control to Arsenal's play. Will either side get a winner this evening? 2-2

70' Triple Arsenal substitution: Kiwior for Gabriel, Jorginho for Partey and Nelson for Smith-Rowe. What do you make of those changes with twenty minutes to go? 2-2

67' There are a lot of elements in this game that require things to slow down a touch, erratic defending and attacking makes a great viewing, but you can sense some control is needed from the Gunners. 2-2

65' What a start it's been to the second half, with four goals already in this tie, it doesn't look like the goals will stop anytime soon with both teams showing potential to win the tie. 2-2

63' Arsenal go close to taking the lead as Vieira's header from Tomiyasu's cross is punched away for a corner. 2-2

62' Arsenal substitution: Tomiyasu replaces Zinchenko.

58' Martinelli goes agonisingly close to levelling the game with a fantastic run through the midfield. The final touch was too heavy, taking the chance away..Who held their breath for that whole run?! 2-1

56' Morita is booked for a challenge on Vieira. The midfielder will miss the second leg due to suspension. 2-1

54' A really disappointing goal for Arsenal to concede after a good start to the second half, you can't say the hosts don't deserve the lead with their quick build up play in advanced positions. 2-1

47' Brilliant chance for Arsenal to go ahead through Martinelli as Zinchenko played a disguised ball through to the Brazilian. His effort was forced out for a corner that was cleared. 1-1

46' Sporting come firing out of the blocks as Turner is forced to make a double save at the start of the second half to keep the score level. 1-1

45' The second half gets underway in Lisbon. 1-1

Talking points at half time: Saliba's fabulous header, Arsenal's defending for the Sporting goal and Martinelli's chance being cleared off the line. A big second half in Lisbon needed for the Gunners with the chance to take a lead back to north London ahead of the second leg.

It was a lively first half in Lisbon as Arsenal looked like they had everything under control after Saliba's opener. The hosts hit back in identical fashion through Inacio to level the tie at the break in the first leg. Thoughts on the first half, Gooners?

KICK OFF: The match is underway in the Round of 16 first leg.

Here we go, the teams are on the field ready for battle at the Estadio Jose Alvalade. Score predictions, Gooners?

Some may have expected to see former Gunner Hector Bellerin line-up against the Arsenal this evening, the Spaniard suffered a knee injury in training this week and doesn't feature in the Sporting squad.

Eddie Nketiah misses out with an ankle injury, Kieran Tierney is unwell, Leandro Trossard is nursing a groin injury and skipper Martin Odegaard travelled but won't feature due to illness. There was some hope that Gabriel Jesus would travel with the squad however the fixture has come marginally too soon for the Brazilian to make his return.

Another look at the Arsenal team as Jakub Kiwior is given his first start for the Gunners: Turner; Zinchenko, Kiwior, Saliba, White; Xhaka, Jorginho, Vieira; Nelson, Martinelli, Saka

Some familiar Premier League names start for Sporting this evening. Ex-Liverpool defender Sebastian Coates is in central defence, former Tottenham academy star Marcus Edwards starts, and former Wolves forward Francisco Trincao completes a strong attack for the hosts.

A strong side fielded by Mikel Arteta, with a heap of first team names lining up this evening. Reiss Nelson gets a well-earned spot in the starting 11 after his heroics at the Emirates last weekend. What do you think of the squad selection?

TEAM NEWS: Arsenal: Turner, White, Saliba, Kiwior, Zinchenko, Xhaka, Jorginho, Saka, Vieira, Nelson, Martinelli Sporting: Adan, St Juste, Coates, Inacio, Esgaio, Gonclaves, Morita, Reis, Edwards, Paulinho, Trincao

Arsenal have faced Sporting Lisbon four times in the past, winning twice and never losing. The most recent meeting between the sides was a 0-0 draw in the Europa League under Unai Emery.
