Arsenal striker Olivier Giroud insists that he has progressed massively this season in the way that he has finally started scoring against teams in the top four.

The striker has scored 18 goals this campaign, in spite of being unavailable for three months with a foot injury. Of the goals scored, five have been against the likes of Manchester City, Manchester United and Liverpool, something that the player has failed to achieve in the previous campaigns.

Giroud will be looking to make a notable contribution against United this time around, having scored the only goal when the Red Devils visited the Emirates in a 2-1 loss for the Gunners. A win here for Arsene Wenger's side will confirm them a place in the top three and let them evade a difficult qualifier to get into the Champions League next season.

Giroud insists that his goalscoring form was down to an increase in confidence, something which he suffered from the lack of in the previous campaigns.

"We all want to score against these [big] teams and it was a great feeling to do it, especially because last season I didn't score too much against the big four. Those were great goals for me and I want to score one more against them," he told Arsenal's Official website.

"I try to bring something to the team. Especially in big games, you need to be ready. Sometimes you have doubts and it's not easy. You miss confidence and everything can go the wrong way.

"But I'm Ok to play with pressure, I have experience with that now and it shows that confidence must be high to be competitive."

"Even if I had a bad injury at the beginning of the season, I came back stronger with a great determination to bounce back.

"We didn't have a fantastic start and we needed a fresh attitude and more determination. I think we were in a good run before the disappointing result against Swansea.

"I hope that we're going to bounce back against Manchester United," he concluded.
