Laurent Koscielny says Arsenal have learnt some crucial lessons from their Capital One Cup exit at the hands of Bradford City.

The Gunners face lower-league opposition for the first time since their penalty shoot-out defeat to the League Two side when they travel to Brighton on Saturday.

Koscielny is confident there will be no repeat performance against Gus Poyet’s side as the team are all too aware of what can happen if they are not at their very best.

“The lesson is that it is not just with your quality that you can win a game,” Koscielny told Arsenal Player. “All of the team must concentrate and want the same thing.

“We must be prepared to fight and stay focused on our quality and play our football like we do in every game. If [we play] like this then we can win every game.”

While Koscielny is wary of the threat Brighton pose, he is confident Arsenal will secure their place in the fifth round of the FA Cup.

Whether it is the FA Cup or the French Cup, it's all the same: the smaller teams always want to win against the big teams

“Whether it is the FA Cup or the French Cup, it's all the same: the smaller teams always want to win against the big teams,” he said.

“They would like to beat Arsenal, so it will be hard and we will have to fight. We must play our football to win this game.

“We are favourites, so there is a little more pressure when you play. It will be difficult but if we keep our quality and play our football, we can win.”
