The France international right-back is out of contract at the end of the season.
A source close to Sagna told the Daily Star: "He will leave 100 per cent for sure unless Arsenal wake up in the next couple of months and offer him new good terms.
"It would have to be in the region of £6m a season on a three to four year contract, plus a signing-on fee of around £6m.
"He wants to finish his career at Arsenal as long as the board give him the right deal."
