Barcelona manager Tito Vilanova has not denied his interest in Alex Song but has refused to comment directly on the Arsenal midfielder.
The Cameroon international is thought to have caught the eye of a number of clubs after a positive 2011/12 and he reportedly wants to explore his options.
Barcelona are thought to be showing the greatest interest in Song and that is said to have motivated Arsenal's interest in Real Madrid's Nuri Sahin.
But after watching his side defeat Manchester United on penalties in a high-profile friendly on Wednesday in Gothenburg, Vilanova would only hint at his transfer targets.
"I don't like talking about players who are not in our squad," said Vilanova when asked about Song.
"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."
