I await eagerly a spreadsheet from you Rob!
Not being funny, but how many differing systems is there for a centre half?
I appreciate you're not really one of e fans with a clear understanding of football tactics, but even you must be able to the difference between 442 and 351 for starters. Berra is a good CB, but he's not good enough for the Prem, unlike a few others in the Championship, so he clearly isn't the best.I don't get the spreadsheet joke. Is this about you spending hours searching through people's posts again?
