LISBON, Portugal (AFP)— Mikel Arteta has called on his Arsenal team to be “ruthless” as they seek to end their away-day blues in the Champions League against Sporting Lisbon on Tuesday.

The Gunners have failed to win — or even score — in their past four European matches on the road.

Their last away win came against Sevilla in the group stages in October 2023.

A narrow 1-0 defeat at Inter Milan earlier this month has left Arteta’s men 12th in the new-look Champions League table.

The Spaniard believes a victory in the Portuguese capital, against a Sporting side who, when still managed by Ruben Amorim, thumped Manchester City 4-1 earlier this month, will prove they belong in elite company.

“It’s certainly something we have to improve,” Arteta told reporters on Monday.

“I think we have made the right steps and, looking back with the way we played against Inter, which is a team that has been so dominant in their league, reached the final of the Champions League (in 2023), which they should have won, to play and dominate that game.

“But the reality is that you have to make it happen and we didn’t.

“Making those steps is what we have to do next. Be ruthless, be efficient in the opposition box and do what we have to do to take the three points away from here.”

Sporting are now managed by Joao Pereira, who has been promoted from the reserve team after Amorim’s switch to Manchester United.

“The run they are on is incredible,” said Arteta.

“That tells you that it is not only the quality, the set-up, the ambition, it is something about the team energy that they have.

“That is a great challenge that we have tomorrow, to come here and make a statement and show we are capable against this kind of opponent. Be ourselves and win the game.”

Kieran Tierney was a surprise addition to the travelling squad.

The Scotland full-back has been sidelined since June after suffering a hamstring injury at Euro 2024.

If called upon, Tierney would make his first Arsenal appearance since the 2023 Community Shield.

“Everybody in the squad is fully fit and available to start the game,” said Arteta.

“We have Kieran Tierney after a long injury, it’s great news that he’s back, he’s been training with the team and he’s at the level to participate.”
