Arsenal's two-goal Alexandre Lacazette warned their Europa League semifinal isn't over after their 3-1 first-leg win against Valencia.

Lacazette struck twice to hand Arsenal a good advantage.

But he insists, "We know it's going to be hard [in Valencia] so of course getting as many goals as we could is better for us.

"I had two more chances where I could have done better but thankfully Auba [Pierre-Emerick Aubameyang] scored the third one.

"We conceded the first goal. We knew they were good on set-pieces and we have to be careful of that in the second leg. But the team showed good character and reacted well, and that's a good thing from tonight.

"We want to win the Europa League to go straight to the Champions League but also to win a trophy. We want to finish in the top four in the Premier League and if we can go to Baku [for the Europa League final] it will be special."
