The Blues, who are close to sending German international Marko Marin to Fiorentina, are hoping to bring in the Viola star for next season.

With less than a month remaining in this summer's transfer window, clubs across Europe are stepping up their pursuits as they hope to grab more of their targets before its conclusion.

Manchester United have been active in the transfer market under new coach Louis Van Gaal as the Dutch tactician seeks to totally overhaul his squad ahead of the upcoming season, and one player that he has been keen on is Fiorentina's Juan Cuadrado.

The Colombian had a good showing at his side's impressive World Cup appearance earlier this summer, but the Viola, who will be competing in the Europa League, are not so keen on letting him go on the cheap, with a price of £50 million set by the club's management.

According to reports, the Red Devils have offered £36 million for his services, especially with Van Gaal planning to ship out players like Shinji Kagawa and Nani as he adjusts his formation.

However, British publication Daily Express claim that with Chelsea's Marko Marin on his way to Fiorentina, Blues coach Jose Mourinho is hoping to use the German as a makeweight in his quest to snatch Cuadrado from his team's Premier League rivals.
