4) A perfect blend of experience and youth
The youth can always deviate from the track if not guided properly. Even if the team possesses plenty of young players at the moment, it is always important to channelize their capabilities and make them function at the very highest level. Player mentoring is a very important aspect in football and the current Chelsea team has no lack of senior players.
There is Willian, who has become the major attacking inspiration most of the time this season after the departure of Eden Hazard and has extensive experience of playing the game at the highest level. His experience will come in handy and can be passed down to hone the skills of someone like Callum Hudson-Odoi, who has been branded by pundits as a generational talent.
Cesar Azpilicueta has been the stronghold of Chelsea's defense and has taken the armband ever since John Terry left the club. He will be vital in passing down all that knowledge to the devastating young wing-back Reece James, whose exploits earned him a place in the Championship Team of the Season while on loan with Wigan.
Moroever there are people in the club like Lampard, Ashley Cole and Petr Cech who can definitely lend an ear to the youngsters and help them become better players in the future. Under their tutelage they will become superstars for sure, considering the amount of promise they have been showing so far.
