Barcelona manager Tito Vilanova has refused to entertain speculation that the club is interested in signing Alex Song from Arsenal, insisting he will not comment on any transfer rumours.
• Busquets talks up Song abilities
• Barca beat Man Utd on penalties
• Mascherano: Tito now has pressure
Reports in the Spanish press in recent days have suggested that the Catalans are ready to swoop for Song, who enjoyed a fine 2011-12 campaign for Arsene Wenger's side.
The speculation has been prompted by Wenger's apparent interest in Real Madrid midfielder Nuri Sahin, but Vilanova remained coy when asked about Song after Barca's penalty shootout victory over Manchester United in Wednesday's pre-season friendly in Gothenburg.
"I don't like talking about players who are not in our squad," Vilanova said. "There are many players outside of Barca who I like and I cannot talk about them. It would be a lack of respect to other clubs."
It is not clear where Song would fit in at Barcelona, who already boast an embarrassment of riches in midfield with the likes of Xavi, Iniesta, Sergio Busquets, Javier Mascherano and Thiago Alcantara among Vilanova's options.
