Atletico Madrid manager Diego Simeone has admitted that Wolfsburg midfielder Diego is the only player that the club are trying to sign this summer.
The capital club have a heavy transfer budget to spend this year following the big-money departure of Radamel Falcao to Monaco, and have made the Brazilian their sole target.
Diego, who previously played for Atletico on loan in the 2011-2012 season, is also keen on a move to the Vicente Calderon.
"Diego is the only player that I have asked the club to sign and I know how hard we are trying to do that," Simeone told AS.
"I also understand the effort Diego is making to come here. We are close and I hope that he will join."
Diego has 33 caps for Brazil.
