Arsenal boss Mikel Arteta says they can be positive about their 2-2 draw at Europa League opponents Sporting CP.
The result leaves the round of 16 tie in the balance.
Arteta said, "Considering you concede two goals away from home and still escape with a draw you have to take some positives.
"But we gave them too much hope by giving the ball away in our own half too many times.
"We had control for long periods but we lacked a bit of that final touch but we are missing four key attackers so we will take the draw.
"At 2-1 we lose the runner and they had a chance to make it 3-1 a lot of things to improve but we showed a lot of resiliency and we are still in the tie.
"Making six changes you lose a bit of the cohesion but we had to make the changes because some are unavailable and others had to play out of position but they did well."
He added, "Everything is still to play for and we get to play at home and now we have to show that we are the better team."
