But they did just fine under previous managers with the 4-3-3. Problem with AVB's 4-3-3 is that he wanted to play an open expansive attacking football, adopting a high defensive line and press all over the pitch. As long as we avoid playing that again, we will be fine. Just go back to the slightly more conservative Mourinho/Hiddink/Ancelotti's 4-3-3 if you like if we are to use it.
