I was at both Chelsea games. Now, I don't remember this being the case in the fa Cup game, but last night, when in possession we played a 4-2-3-1; however, when out of possession, veltman slotted into the centre, minteh dropped to RWB into a new 5-3-2-0 formation. This was either an attempt to shore up more broadly defensively, or, specifically, provide depth and cover in the full back positions, where we'd been getting continually overrun all season. We've been highly effective against the top sides (who are more open and offensive), yet highly ineffective and naive against the lesser prem teams. Will be interesting to see whether we persist with these dynamic formations in the next few games.
