5. John Terry and Ricardo Carvalho
Two of Chelsea's finest defenders formed quite a partnership to make history for the club.
It was under this pairing that Chelsea recorded two successive Premier League titles, and a League Cup.
And in the 2004-05 title triumph, the Blues racked up a whooping 95 points - the most ever in the Premier League - and it was down to Terry and Carvalho that they conceded just 15 goals in 38 matches that year.
