I guess you should follow your own advice. Buying players doesn't mean being in transition. If Barcelona or Ajax buys 22 new players they will still be playing the same way and getting some sort of results because the way of playing will stay the same. We don't have this sort of identity so new coach, new system and new players means time for building a team. The same is happening with City and MU this season. If you think that sticking 15 good players and good coach in the same team means instant automatic results you seriously need a reality check - or just go study recent history of Real Madrid which is a great example of how amazing players and good coaches guarantees you nothing.
