Arsenal captain Martin Odegaard admits they must be stronger tonight against Porto.
The Gunners host the second-leg of their Champions League round 16 tie trailing 1-0 on aggregate.
Odegaard said: "We weren't good enough, it's the only away match we haven't won in 2024, I think it's enough motivation to come back and show a different face tomorrow.
"We're all very ready and excited.
"We know how good we are when we play to the best of our ability and that's what we'll try to do tomorrow, let's think about it.
"It'll be a fantastic environment."
