Atletico Madrid are close to complete the signing of Bayer Munich striker Mario Mandzukic, reports in Spain claim.

The Croatian international's future with Pep Guardiola's side has been under scrutiny since the German club announced the signing of striker Robert Lewandowski earlier in the year and recently Mandzukic recently confirmed he wanted a move away.

"I met with (Bayern chairman) Karl Heinz Rummenigge before the cup final and told him I wanted to leave the club. I've had a fantastic time at Bayern. It's a great club and I never thought I'd want to leave, and especially not at this point in time." Mandzukic said.

"But, let's be honest, I cannot play to my strengths under Guardiola's style - no matter how hard I try. I realised that after the 1-0 defeat by Real Madrid in the Champions League semi-final first leg and, that being the case, it's best for all parties that we go our separate ways."

Even though he has been Bayern's top scorer for the past two Bundesliga campaigns, Guardiola left him out of the squad for the German Cup final against Borussia Dortmund which worked to increase Mandzukic's frustration.

Arsenal and Chelsea have been linked with the Croatian international's services in recent months but according to Marca the wantaway striker will eventually join the Vicente Calderon side to cover the vacancy left by Diego Costa's move to Stamford Bridge.

Marca claims the La Liga champions have already offered €18m (£14m) and though Bayern are negociating, the deal could be close in the coming days.

Having lost both Costa and David Villa, Atletico are desperately looking to bolster their attack and they are also trying to sign Alvaro Negredo.

However, with Manchester City unwilling to negotiate a deal below £25m, Marca claim that the Spanish giants are acting quickly to complete a deal for Mandzukic.

Arsenal and Chelsea are also reportedly fighting for his services.

Arsene Wenger is still yet to make any additions this summer while Chelsea boss Jose Mourinho is considering signing after the release of Samuel Eto'o, while Fernando Torres and Demba Ba's futures are still up in the air.
