John Terry, Frank Lampard and Ashley Cole have all been crucial to Chelsea's success in recent seasons, but the English trio now find themselves entering the final six months of their current contracts.
Despite the relative lack of action for the trio, these are three players that have had a huge impact on Chelsea's success.
And it is certain that should Chelsea fail to renew their deals, all three would have many clubs queueing for their signature in the summer.
Have no doubt that should this be allowed to happen, the Chelsea faithful will voice their opinions loudly as they have done in the past when they have disagreed with the choices of their club, with the sacking of Di Matteo and appointment of Benitez a clear example of how strongly they can feel on matters.
To let such huge influences at the club leave would be shocking, but to let them walk away for free after such service and commitment to the club should be a criminal offence.
Teams do need to evolve rapidly, no more so than in this day and age where the competition is so intense, both at home and in Europe.
And with some of their youthful signings such as Oscar and Van Ginkel, there is evidence that Chelsea are trying to achieve this.
But to cut out the experience that Terry, Lampard and Cole can still offer could have a huge effect on the Chelsea dressing room.
With Lampard now topping the Chelsea scoring records as well, there is no doubt that Mourinho would want to hang onto such experience and ability.
And Mouriniho is confident that there will be no issues with their contracts.
"Everything is very calm [and] at the end of the season, probably before that, the offer will be on the table." Mourinho said on BBC Sport.
"It's a situation that doesn't worry me or the club and, I think, doesn't worry the players," he said.
But fans at the Bridge will surely be hoping that it is a situation that is resolved sooner rather than later.
