The 32-year-old has been frozen out at the Nou Camp and has hinted he expects to leave Barcelona at the end of the season.
He said last month: “I have already enjoyed many new adventures, so I don’t know what will happen in the future.
“I think that I have done well at Barca in these last four years.
“But we’ll see what happens.”
Keita is aware of Liverpool’s interest in signing him this summer.
