Arsenal midfielder Francis Coquelin was delighted after his side's 3-0 win at the Emirates against West Ham United on Saturday.
The 23-year-old was again impressive in the Arsenal midfield against West Ham United, adding steel in front of the defence.
And he believes the Gunners have enough quality to turn around the 1-3 deficit against Monaco on Tuesday night.
"It was a big blow when we lost 3-1 at home against Monaco," Coquelin told the club's official website.
"I don't think anybody expected that but I think we pulled ourselves together, went to Manchester United in the FA Cup quarter-final and won 2-1 in a big game.
"It was another great performance against West Ham.
"Qualifying for the next round looks impossible but you never know in football. Hopefully we can get a great a great result over there and then move on to the next game.
"There's quite a lot of things to change after you lose 3-1 at home, but we've done that in recent games. We haven't conceded many goals and we've been scoring goals as well.
"We haven't lost a game since Monaco and the confidence is high. We're going to go there with great spirit and I think we can turn this result around."
