I think, and its only a hunch, that Mourinho probably thinks that short term-ism harmed his changes of landing the United job - nobody can convince me he didn't want it. I reckon he'll try to lay down roots at Chelsea in an attempt to show (not necessarily us but himself) that he can build teams over and over whilst staying competitive, that he can use the academy and that he can stay somewhere longer than three years. Whether or not he achieves it is another issue entirely, not just because of Jose's own inevitable controversies but also Roman's unrealistic expectations as an owner and his short sightedness. I think Mou will try to approach this one differently though.
