Barcelona coach Pep Guardiola insists he doesn't need to buy this month.

Maxwell has been sold to PSG, while David Villa is out injured and Seydou Keita is away at the African Nations Cup.

But Guardiola says: "We'll stick with these players to the end. It's not a good idea to look to the transfer market because new players have to settle in and it costs money.

"The reserves are the cheapest, most productive and sustainable solution."
