Now its official, Seydou Keita has become the first Malian to wear a Barcelona shirt. Barcelona paid the 14 million Euros release clause in Keita's contract to Sevilla. He signed the contract which will officially see him in the club until end of June 2012. The release clause has been set at a whooping 90 million Euros. The Mali international has thus become the first signing after Guardiola took charge. He may soon see his team mate Alves joining him at Barcelona. Keita has also become the ninth African player to join Barcelona.Keita started his top flight footballing career in 1999-2000 seasons at Olympique Marseille. But shortly he was transferred to FC Lorient, where he completed his transformation to a quality defensive midfield player. Then he moved to RC Lens in the 2002-03 seasons. The 2006-07 seasons were so productive for him in terms of goals and success - he scored 11 goals in 37 games. But Lens has to let him go reluctantly after Keita reached an agreement with Sevilla. He continued the good work in Sevilla also scoring four goals from 31 games. But his ability, skill and his track record with buy-out clauses should be the reason why Barcelona has set a huge release clause for him. Whatever this one is a quality striker. he will be able to fill into the shoes of Edmillson and cover the great void in midfield. But how Guardiola is going to use both Yaya and Keita together is to be seen. Keita and Yaya both are quality players and will demand regular first team actions. Add to this Xavi and Iniesta who will be the driving force in Midfiled, Guardiola might be in for something.
