Barcelona president Joan Laporta insists they're capable of buying in January.

Laporta says they'll be active if new coach Xavi requests midseason additions.

He said, "Reinforcements in January?

"We will try to strengthen the team if the coach asks for it, and he asked us to, but we don't have the pay margin at the moment and if we don't have it, we cannot sign.

"We have to let the director of football work."
