Barcelona coach Tito Vilanova admits they're in the market for a new centre-half.

Vilanova says he's keen to keep juggling his squad ahead of the summer market deadline falling.

"It would be great to have a defender that can also play in the pivot role, but if we can't find anyone we'll go with a player from the reserve side, that has always worked out well for us," said Vilanova.

Asked about interest in Athletic Bilbao's Javi Martinez, Vilanova added: "It's not time to talk about specific players. Javi Martínez can play in both of those positions, but it all depends on the Club's capabilities. In Europe there are 50 or 60 players that can play in both these positions, and if we can't find one, we'll go with a reserve-side player."
