Barcelona stars Lionel Messi and Daniel Alves were involved in a bust-up with fans at their London hotel, just hours before their Champions League defeat at Chelsea.
The incident was sparked when three fans who were staying in the same hotel as the Barca squad approached Messi for an autograph.
James McWatt, 19, from Manchester was in London on a shopping trip and told The Sun he met Messi and Alves in the corridor of the Grosvenor House Hotel, where he asked the Argentine star to sign a shirt he had bought specially.
Messi was going to oblige but James says Alves intervened and began shouting at him and his two friends Ryan Hill, 18, and Steve Carruthers, 21.
