Manchester United boss Jose Mourinho is chasing Borussia Dortmund midfielder Marco Reus.
Don Balon says Mourinho is desperate to sign the German attacker.
United need to bolster their attacking options this summer.
Wayne Rooney looks set to leave Old Trafford at the end of the season and Reus could fill the void.
It's suggested the 27-year-old could be willing to leave his homeland.
Along with United, Atletico Madrid are also interested in Reus.
