An Arsenal fan has managed to get Tottenham Hotspur reprimanded by the Advertising Standards Authority.
Tottenham Hotspur have been criticised by the Advertising Standards Authority (ASA) over making potentially misleading claims over their new stadium.
Spurs ran a series of adverts last year describing their new ground as 'the only stadium to watch Champions League football in London'.
It was designed as a witty dig at rivals Chelsea and Arsenal who failed to qualify for the competition.
The problem is that Tottenham failed to meet their planned September 15 opening date and had to switch all of their group games to be held at Wembley.
It is currently unclear whether Tottenham's stadium will be ready for the last 16 next February.
Likewise Tottenham are at risk of failing to qualify and must win against unbeaten Inter Milan at home and then avoid defeat away to Barcelona in order to reach the knockout phases.
Spurs could end up playing in the Europa League in their new stadium, the 'prize' for finishing third in their group.
BBC Sport report: "Two complaints, including one from an Arsenal supporter, were made to the advertising regulator."
An ASA spokesperson said: "This case was assessed and dealt with via an advice notice.
"In this instance, we contacted Tottenham Hotspur and advised them to avoid making claims in future advertising that they cannot fulfil; to avoid disappointing customers. We also advised them that if the ad is still appearing to ensure it is removed."
