Chelsea's biggest problem is that they don't have a regular squad. This leads to instability in the team. At the same time, Chelsea are paying the price of having players with great potential in their squad, but none of these players are living up to their potential. Chelsea also don't have players like Lampard and Terry to own the team. Chelsea have made nearly 30 signings in the last two years and none of them have contributed to the team. It's a complete chaos. The team needs a top mind and Chelsea will have to deal with problems for many years to come.
You are speaking facts and if Chelsea does not resolve this issue on time, we may watch a failed and struggling Chelsea for years to come from now. They have made a lot of signings despite the large number of their players playing as loan players in other clubs and still nothing is working out for them. Sometimes I fell they need to sign young players and maybe they may have a long time strong squad like the time of Lampard, Drogba and Terry. If the big players are not willing to effect the change needed by the club, they should try young players too. Chelsea has the funds and getting young players for long time contract shouldn’t be an issue for a club like Chelsea.
