Arsenal frontman Olivier Giroud believes that the Gunners will need to stick to their guns if they want to beat Barcelona.

The two clubs will face off at the Emirates Stadium on Tuesday night, and the Frenchman will be looking to draw inspiration from the Gunners' group stage win over Bayern Munich from earlier this season.

Giroud said: "We would love to beat them because they look unstoppable.

"We need to play our best game and being all together and at 100 per cent, of course. Otherwise we're not going to play this game to lose it.

"We are confident, we need to be confident and play the Arsenal way. After, we'll see. We did well against Munich. We know that we can beat big teams but there is one thing for sure: that we need to be at 100 per cent and determined.

"I think it will be a different game than against Bayern. We can do very well in the Champions League. We just need to focus and give 100 per cent all together with good team cohesion.

"After that we will put what we need into this game - a lot of commitment and determination. We managed that against Bayern and that will help us to win tomorrow.

"When you play this sort of game, you need to be focused on the game and forget the importance of the game. We are not favourites so we can maybe take the pressure off our shoulders."
