Wolfsburg star Ricardo Rodriguez could be the subject of a head-to-head battle between Manchester United and Real Madrid this summer.
According to German publication Bild, the Premier League and La Liga outfits are showing significant interest in the 23-year-old Swiss left-back and both are set to go after him at the end of the season.
United have long been linked with Rodriguez, particularly since Luke Shaw suffered a badly broken leg earlier this season, and could make a play for his services but will have to go up against Real who want to provide competition for Marcelo.
Rodriguez has been one of the most promising full-backs in Europe since joining Wolfsburg from Zurich in 2012 and admits he would one day like to take the next step and play for a big club.
"Wolfsburg is a super club, and I'm still young," he said.
"But I have a goal, as a football player, and that is to win titles regularly and be playing as a top, top club."
The 33-time Switzerland international has made more than 140 appearances since his arrival at the Volkswagen Arena.
