How to stop Falcao?

Hi there i just got Fm 13 yesterday and i started a game with Barca as they are my team. First few games went well and i beat Real in the supercup then i played against Atletico Madrid. So far this season i have had a good defensive display only conceding two goals and both were against real madrid. But then i played Atletico and Falcao absolutely tore me apart, It was actually one of the best games i have had in a while i ended up beating them 5-4 Messi got a hat trick, Rodrigo got one and the other was an own goal. But for them Falcao scored four. I am not surprised because he is a great player and Barca's defense right now is far from perfect. Just wondering if anyone has any ideas of how i could keep him out next time we play without buying a new centre back which i plan to do at the end of the season when i get more money.

What kind of goals were they? If they were all assists from one specific area (i.e. right wing crosses) then you can adjust your tactics to stop that from happening. If not then I guess the only real options are playing in a more defensive way or using a formation with more defensive cover.

He moved to Man City in my United game, just played against them and he scored twice, so I'm guessing he'll be a problem no matter what you do to stop him.
