I had a season like that, My first season for Man Utd, finished on 97 points and got 30 wins I think, then got 90 in my second so a bit poor but won the Champions League, League Cup and obviously Prem
Been using your 4-2-2-2 C for a few days now, only played it for about 11 games though but had some big scalps already (Livs, Inter, Porto). My only worry is using it against Chelsea but i'll just deal with that when the time comes.
As a fact I'm quite happy to discover it's working for minor teams. I'm used to make tactics for strong teams able to do a lot of rotation because I really push the tempo, runs and such, making them always be quite tired by the end of the matches.
