Barcelona coach Tito Vilanova has refused to comment on the Catalans' alleged interest in midfielder Alexandre Song, as he feels it would show a lack of respect towards Arsenal.
Sergio Busquets and Andres Iniesta recently voiced their admiration for the Cameroon international when asked about his qualities, but the newly-appointed trainer chose to avoid being drawn in on discussing a rival team's player.
"I prefer to not talk about players that are not part of the Barca team. I think it is disrespectful to other teams if we talk about players that are not part of Barcelona," Vilanova told reporters.
"Whoever comes must be a good player, that is what is important. There is no rush."
Song, now 24, has developed into an important first-team member at the Gunners since joining them from Bastia in August 2005.
His contract with Arsenal runs until the summer of 2015.
