Jose Mourinho says it is of growing importance that Chelsea retain a core of local players that can help foreign stars blend in.
Chelsea brought in a total of eight players in the transfer window with nationalities ranging from Chile to Ghana but no Englishman were recruited.
A core of long-standing British talent is growing in to its twilight years with Frank Lampard, John Terry and Ashley Cole all 32-year-old or over.
It left many wondering whether Mourinho would be able to replace these players with English equivalents but the manager has confirmed his intention is to blend a core of local talent within the squad.
Speaking at a Barclays community event, Mourinho said: "I like the fact the foreign players arrive and find a spine in place, a nucleus of local players who can tell them and explain to them where they are, how things work here, the way they have to behave, and even the way they have to play in this league.
"They have to understand what they've joined.
"For example, an English player knows what it's like to play eight matches in three weeks at Christmas time. For a foreigner, that can come as a shock, so you need locals around who can explain what it means to people, why you can't complain and why you have to buy into it.
"Ideally it's not just about having British players either, but having players who are made in Chelsea.
"In three or four years' time, if we don't have other Englishmen to replace this nucleus of players – when Lamps is 39, John is 36– I will be very sad. Every club needs that.
Obviously replacing the mercurial pair Lampard and Terry is easier said than done. The long-standing Chelsea players. The pair have over 800 appearances for the Blues between them as well as 180 caps for England.
But Mourinho insists Chelsea are working hard on developing new stars to take their place.
He continued: "We are working on that (new generation). We have some players on loan, like (Nathaniel) Chalobah, and we have some others working and growing in the under-21s.
"Their standard is improving. Before, these age groups in England did not have a good level of competition at that age, but now there is a national championship, an under-19s Champions League, and it's improving them."
