Both the Blaugrana and the Andalucian outfit announced the deal
on their official websites following the player's decision to send
a fax cancelling his employment contract.
That move meant that Barça will now have to pay €14m as part of the
terms of the clause in his contract only a year after he signed for
Sevilla for €4m from Lens.
Keita has put pen-to-paper on a four-year contract at the club's
offices in Barcelona and the deal sees his new buy-out stand at a
staggering €90m.
