Arsene Wenger has revealed that he has no idea who finished the Manchester City game as the Arsenal captain after Laurent Koscielny was forced off the pitch due to his Achilles problem. The Gunners were trailing the game 2-1 at half time and came back after the break to level the scores with a towering header by Shkodran Mustafi.

According to Premier League rule M.11, a captain has to wear the armband at all times, which was not the case in the second half, when Koscielny was not on the pitch. Per Mertesacker is the designated captain for the Gunners, but the German has not been involved since the start of the season with a knee injury he picked up during pre-season.

Wenger insisted that they would select a captain for their game against West Ham. If the Gunners are found guilty of not fielding a captain in the second half, they will be spoken to by the FA, but any sort of punishment is unlikely.

"I don't remember," Wenger said, as quoted by Sky Sports. "It is a good question. Nobody asked me who is captain. I will have 24 hours to think about that."

The Gunners are currently sixth in the table, seven points adrift of fourth placed City, with a game in hand. They face the Hammers on Wednesday, 5 April, having won only one of their last six league fixtures, losing four of the same.

The north London club will be wary of the threat posed by Andy Carroll, who scored the solitary goal for the Hammers in the reverse fixture at the Olympic Stadium. Wenger believes that the best way to keep the England international at bay would be to play in the opposition half.

"The best way to keep him quiet is to play in their half," Wenger told Arsenal's official website. "Apart from that, Carroll's strengths are that he protects the ball well, he's good in the air, he's very forceful with his commitment as well, so we will need to be good to stop the crosses. Once a cross comes into the box, he's always very dangerous against anyone."
