To me the best side to ave ever played the league, may it be premiere league, la liga serie A and so on, the chelsea side under jose Mourinho was the best ive seen! they were rampant, wid an aggressive intent and attitude and still hold the record for the highest number of points in a season in the PL and all this under the special one's new reign.. as in in hez first 2 seasons! they were unbelievable! 

Mourinho is a legend... very clever man.... as you can see....

One of the best coaches but his attitude is pretty bad.
