Chelsea's qualification process is very good, it comes from a few seasons ago where they had many failures but they persisted until they found success, I remember how they changed coaches, players, trying and trying, until they finally got results, I think that this process should be copied by MU, which for me is a team that has declined a lot as time goes by.
I think even if Manchester United want to copy Chelsea’s process of reviving their squad it will be really difficult because of United’s financial situation currently. For United to be able to make notable changes they will first need to overhaul their squad, giving way for incomings before they can make any significant changes and I think that is the stumbling block holding them from making signings currently.
They generally haven't made any good transfers lately, yet they're trying to actively cut costs at the club. I don't know what the model is, maybe they're coming up with something grand? A new model for running the club? Personally it looks incredibly cheesy to me if so, but I think it's much simpler than that - the management don't care about the league position, they need to cut costs as much as possible and keep to averages, so it's unlikely we'll see any changes any time soon.
