However, the incident was included in referee Chris Kavanagh's match report and will be reviewed further.

Arsenal's win helped them maintain a five-point lead at the top of the Premier League.

Bournemouth had taken the lead after just nine seconds through Philip Billing before going 2-0 up in the 57th minute thanks to a Marcos Senesi header.

Arsenal manager Mikel Arteta's side launched their comeback with goals from Thomas Partey and Ben White. Nelson then won the match with virtually the last kick of the game, with substitutes and members of coaching staff running on to the pitch to celebrate with the 23-year-old.
