The Gunners won 4-2 last night to reach the final 7-3 on aggregate.
Former Arsenal midfielder Coquelin said afterwards: "Falling at home hurts, the fans deserved better than this result, we started the match very well and it was a shame to concede the goal in the first-half they had...
"When you concede seven goals in two games you cannot pretend to win the tie, now there are three finals, the Cup is very important for us."
On Arsenal strikers Pierre-Emerick Aubameyang and Alexandre Lacazette, he added: "We have competed against a team of great strikers, they have a high level and if you leave a minimum space ... They deserved the victory and now we are going for the remaining matches."
