Manchester City have lined up a new bid to further their recent attempts to lure Barcelona talisman Dani Alves to the Etihad Stadium ahead of the start of next season’s Premier League campaign.

The Premier League champions are understood to be offering €15million and Aleksandar Kolarov to seal a deal for the Brazilian defender.

Spanish newspaper Sport have reported City have been pushing aggressively to sign the 29-year-old.

Alves is also being linked with a number of German clubs,

Roberto Mancini told the Daily Mail: “Barcelona and Real Madrid every year buy two or three players and spend a lot of money,

“I think for Manchester City it will be the same. We need to improve. We need to have the strength to play Champions League and Premier League.”

Alves joined Barcelona after spending a successful six year spell with Sevilla, in his time with the mid-table La Liga side he won two UEFA Cups and the Copa del Rey. The defender joined Barcelona for €32.5m, which is a record transfer fee for a defender.

The Brazilian has been a mainstay in the Brazilian national side since 2006, he earned his first international cap in a friendly against Ecuador. He has since gone on to make 55 official appearances for Brazil, with the defender hitting the back of the net 5 times in the process.
