Arsenal manager Mikel Arteta is bracing for a tactical battle in Wednesday's Champions League quarter-final second leg, fully expecting Sporting CP to alter their approach after last week's narrow 1-0 defeat in Lisbon. With a precious but fragile lead, the Gunners know the job is only half done.

Sporting have already shown their resilience in this competition, famously overturning a 3-0 deficit in the previous round. That history ensures Arsenal can take nothing for granted at the Emirates Stadium, despite the advantage of home support. Arteta acknowledged the Portuguese side's quality, stating, "We knew that, they proved that in the first leg, and that’s why we know that tomorrow it’s going to be a really tough match."

The Arsenal boss anticipates a shift in Sporting's game plan. He noted their typically dominant style but warned of their adaptability, saying, "Regarding the [first-leg] result, they will modify that, and we are ready for that as well. We will apply what is necessary to win the game." While a draw secures progression, a convincing victory is the clear objective.

This match carries extra significance for Arsenal's packed schedule. With a monumental Premier League clash against Manchester City looming on Sunday, the ideal scenario involves efficiently securing the tie early to conserve energy and focus. The Gunners will be desperate to avoid a draining 120-minute ordeal and instead aim to control the tempo from the outset, blending tactical discipline with the attacking flair their fans have come to expect this season.
