The fullback admits he's likely to leave on-loan again next season.
"Every player has different paths and mine so far has been out on loan," said Bertrand, who has seen under-21 team-mates Scott Sinclair and Michael Mancienne give up hope of making the grade at Stamford Bridge this season.
"You've seen the benefit for Scott. He's gone up this year with Swansea and it's been fantastic for him."
But asked how long he was prepared to wait for his own chance at Chelsea, Bertrand said: "I'm just concentrating on the near future."
