Captain Laurent Koscielny went off injured at half-time against Manchester City on Sunday

Arsenal appear to have broken a Premier League rule after failing to nominate a captain in the second half of Sunday's game against Manchester City.

Laurent Koscielny led the side in the first half for the 2-2 draw at the Emirates but came off at half-time and did not appear to have been replaced by a nominated skipper for the second half.

Under Premier League Rule M.11, a captain must wear an armband at all times.

An Arsenal spokesperson told Sky Sports News HQ it is unclear whether there was a captain in the second half but Theo Walcott was the senior player on the pitch.

Sky sources understand if there has been a breach, the Premier League will remind Arsene Wenger's side of the requirements and take no further action.

Gunners captain Per Mertesacker is currently injured, as well as vice-captains Santi Cazorla and Petr Cech.
