Barcelona are reportedly keen on signing Manchester United target Marco Reus and, according to Catalan reports, the Spanish giants have already reached an agreement with the Borussia Dortmund attacking midfielder.

After Dortmund lost star striker Robert Lewandowski, reports suggested Reus may be next to seek a new challenge as the winger refused to commit his future to Borussia, saying: "It's like that in this business. Every player only has one career and wants to get the best out of it. You have to decide what's best for you. We'll see about that."

The 25-year-old - who has been a key player in the success enjoyed by Jurgen Klopp's team, scoring 16 goals and managing 14 assists in 30 league appearances last season - has also found himself linked with a move to Old Trafford, with recent reports suggesting United coach Louis van Gaal will make Reus a priority target. However, last month the Germain international insisted he is likely to stay at Borussia Dortmund for next season.

But Catalan newspaper Sport claims Barca lead the chase for the player and the club have already reached an agreement with Reus – but they still have to negotiate with Dortmund.

However, Barca's main target is Manchester City's Sergio Aguero. But given the complexity of the transaction - the English club refuse to negotiate and so the player could only depart by submitting a transfer request - Barca's sporting director Andoni Zubizarreta has earmarked Reus as a back-up option.

It is thought that Reus has a release clause of £29.4m, much lower than the Argentine's.

Also Aguero insisted he has no intention of leaving the Etihad Stadium this summer after their Premier League title triumph, saying: "I am so happy. It was an amazing moment to win another title. I will be back next year even stronger to win more trophies."

Barcelona have already agreed personal terms with Sevilla's Ivan Rakitic over a €20m move. For the full story, click here.
