After defeat to BATE Borisov, Arsenal boss Unai Emery assured fans they'll be stronger in the second-leg of their Europa League tie.
The Gunners lost 1-0 after Stanislav Dragun nodded home Igor Stasevich's free-kick for the game's only goal just before half-time.
Emery said: "Next week we are going to play another 90 minutes and I am sure it is going to be different. Today the first half was a good performance for us, we had chances to score, sometimes last week our chances brought a goal and today they did not.
"We worked. I am happy with the players as we worked and we tried. They struggled also defensively when they were 1-0 up - and they are organised and a competitive team.
"Our big chance, our big opportunity and challenge is next week. I trust in our players and I trust in our stadium and supporters."
On Alexandre Lacazette's red card, he added: "I didn't see the action but we spoke and frustration needs controlling. It's bad news with the red card. Next week we aren't going to play with him but now we are going to think with the players that are OK for next week."
