Tottenham say they have ‘grave concerns’ that the punishment dished out to Barcelona over treatment of away fans during the two sides’ Champions League meeting last year is too soft.

Uefa’s disciplinary panel found Barcelona guilty of ‘insufficient organisation’ of the group stage clash at the Nou Camp in December, after incidents in which stadium security staff used excessive force against Tottenham fans.

The Spanish giants were fined €20,000, but a spokesman or Spurs said the punishment was not severe enough.

“The safety and wellbeing of our supporters is paramount to the Club when traveling both domestically and overseas,” the statement read.

“The treatment our fans received in Barcelona some six months ago was completely unacceptable, something UEFA has acknowledged, and some are still recovering as a result of this ordeal.

“We went to great lengths, along with the Tottenham Hotspur Supporters’ Trust, to gather evidence so UEFA could take appropriate action. We thank them for assisting us in gathering the necessary information.

“No visiting supporters should have to experience what our fans went through that night again. We have grave concerns, however, that the punishment imposed will not act as enough of a deterrent to avoid a repeat.”
