Manchester United are considering a double move in signing AS Roma midfielders Miralem Pjanic and Radja Nainggolazn, according to the Mirror.

The Italian club have been hit with a fine of €6m (£4.3m. $6.8m) after a UEFA investigation showed non-compliance with Financial Fair Play (FFP) break-even regulations. They were one of the 10 clubs to be hit with a fine.

Roma needs to reduce their squad size from 25 to 22 players for the next season. They have reached an agreement with UEFA, where they have to report an aggregate maximum break-even deficit of €30m (£21.7m, $34.7m) for the financial years ending in 2015 and 2016.

Pjanic has been in fine form for Rudi Garcia's side, scoring five goals and managing nine assists in 31 league appearances this term. Meanwhile, Nainggolan has been impressive in the centre of the park, especially in the absence of injured midfielder Kevin Strootman.

The Bosnian star and Nainggolan are valued to be around £66m ($103.7m). Roma could be forced to let their star players leave the club in order to balance the books and also reduced the number of players in the squad.

Pjanic and Nainggolan are the two star players at Stadio Olimpico and their sale in the summer transfer window will help the club to generate a lot of funds. Louis van Gaal is looking to bolster his midfield and he is in search of players who can strengthen and also bring balance to the team.

United currently have Michael Carrick, Daley Blind and Ander Herrera, who can play in the central position. In addition to this, the former Barcelona and Bayern Munich manager has deployed skipper Wayne Rooney in that position.

An approach from the 20-times English champions for Roma's two key players could force them to sell Pjanic and Nainggolan. The pair have been linked with a move to Old Trafford even in the past.

Meanwhile, Liverpool have also registered interest in the star midfield duo as Brendan Rodgers is in search of a replacement for Steven Gerrard. It should be seen if the Reds can challenge their arch rivals United in securing Pjanic and Nainggolan's services.
