Take out the Morinho factor and add a manager a couple of tiers down from that, allied to other clubs having way more money, and Russian riches become far less appealing than when he first arrived.
Doubt the 'Mourinho' factor will help United too much either tbf unless it is in attracting players who played with him at Inter which is just about the only major club he left as a hero. This is not 2010 anymore as Tyton mentioned a few weeks ago.
Agree that Chelsea is far less of an attractive prospect than it has been for many years but what a lot of people forget is that we already have a very good squad in place. It just needs the addition of 2-3 quality players in the right positions to make us seriously competitive again. We also some very good young players to supplement the squad such as RLC, Betrand Traore, Kenedy, Zouma and Christensen which traditionally has never been fully utilized by Chelsea managers. We are in a much better position than most people would like to think but still got a long way to go.
