West Bromwich Albion striker Saido Berahino has reportedly been filmed taking laughing gas from a balloon.

The 21-year-old has emerged as one of the top strikers in the Premier League this season following his exploits for the Baggies, despite the club's struggles.

However, footage has been revealed showing Berahino inhaling gas from a purple balloon, which allegedly contains nitrous oxide, according to The Sun.

The clip emerges just a week after a similar video was released of Liverpool winger Raheem Sterling apparently inhaling a legal high also from a balloon.

Berahino has scored 12 goals in 33 appearances in the Premier League this season.
