The three at the back was a disaster when implemented, for the simple reason that we never had the personnel to make it work. Almost to a man, it didn't suit our squad. We haven't got the wing backs with pace who can tackle and cross. The ones who can tackle cant cross, and vice versa. Our best centre halves work as a solid duo and aren't at their best spreading out and having people run into the channels. Whilst it might have some merit as a change formation when trying to break inferiour teams down - and this is where it ended up being used - it was the wrong formation for the champions league and out early league games. It left us exposed to well drilled teams on the break.
In fact I think playing it all close season and regularly during the first couple of months of the season was a major contributor in getting our season off track. We played for those first few months with 3 and 4 different systems every game, a huge turnover of players and couldn't find any rythmn. In some ways we never recovered.
A big managerial mistake to dive into this season leaning so heavily on this untried system.
I don't think you necessarily have to be able to corss the ball as a wing back. If we have Agüero and Tévez up front, what's the point in crossing the ball in from wide?
What wing backs with paqce can give you is a drive into the box that can cause havoc and either end up in a shot at goal, a cut-back pass or being brought down by the defender. It also provides the width that spreads defences wider across the pitch when they're trying to defend narrowly and tighten up any space. When you spread them wider there becomes larger spaces in the middle and there are more opportunities to shoot or run into that space.
