Chelsea were always a tough team to beat in the Premier League, but since they've had investment they've become an elite team both domestically and in Europe. Jose Mourinho's men pride themselves on wearing the blue soccer jerseys, and it's that discipline that has helped the club develop previous star Didier Drogba and current No. 1 goalkeeper Petr Cech. With Jose back in town, many believe they will win many more trophies for a long time. Jose's always been one to move from team-to-team, but it's clear both the club and manager want to create a Sir Alex Ferguson-Manchester United kind of relationship, which will revolve around longevity and loyalty. Can Chelsea dominate the footballing world for years to come? If so they will need to replace some of their ageing stars.
