Sportswear giant Adidas has been left red faced after a Manchester United jacket and a pair of Chelsea trousers were advertised together online.
Adidas sealed a record £750m kit deal with United last year, but they were in danger of upsetting the Premier League giants in a recent ad.
On the company's website, a retro United jacket was advertised by a male model, but he also happened to be wearing a pair of Chelsea-branded trousers, according to The Mirror.
After fans spotted the blunder, Adidas removed the ad from its site.
