Arsenal striker Olivier Giroud believes that he and his teammates face a difficult task against Middlesbrough in Sunday's FA Cup fifth-round tie at the Emirates.

The holders will face Championship opposition, who booked their place in this fixture with a 2-0 victory over Premier League champions Manchester City.

"If they are here it's because they succeeded in beating a great team like City, so we need to be aware of that," Giroud told Arsenal Player. "We need to play our game straight away from the beginning and not let them take confidence.

"It will be a tough game, especially in the FA Cup. We know that even though a team is playing in an inferior division, they will really want to beat us at home, especially Arsenal. We are really cautious and we want to start the game on the front foot."

Arsenal sealed their place in the fifth round with a 3-2 victory over Brighton & Hove Albion.
