Arsenal defender Koscielny enjoys one-on-one duels
Arsène Wenger recently said the centre-back thrives when he shows authority in his game, and Koscielny says his manager is right.
"I need to have duels and win them," he told Arsenal Player. "It's better for my game because I am more confident, I can take little risks with passes and feel better and better during the game.
"The boss is right with this. Now it's up to me to keep this all the time.
"I'm in a good position because I'm fit and I'm confident. I think every player wants to finish high up in the table. I will give everything for the squad to finish in the Champions League places."
