Chelsea have a club footprint?? Did you watch pre and post-Mourinho Chelsea? It's not about style at this point; for all the talk of tactics and philosophy, football is ultimately played inside the players own heads. Removing Van Gaal might just relieve a lot of pressure, and allow them to just play without thinking to much. It might go horribly wrong, certainly, and perhaps 3 months is too long to leave a caretaker in, but from my memory we played with a great deal more swagger after we sacked Moyes. I don't see why we couldn't get the same effect again.
