shadow of his former self
Chappell said Tendulkar had been a shadow of his former self in the last three or four years and has looked like a player trying to "eke out a career".
In his column for Mid-Day newspaper, Chappell said now that India was knocked out of the World Cup, one of the major decision would be about Tendulkar's fate and he suggested the batting icon to hang up his boots
Please explain the highlighted group of words.

To eke out a career means to put in a lot of effort to make a name for yourself.
