Man Utd identify number one transfer target

Manchester United have made Roma's Miralem Pjanic their number one transfer target this summer, according to El Mundo Deportivo.
The 26-year-old is signed on to his current side until 2018, but many clubs are believed to be willing to splash out and meet the players €40 million buyout clause.
The other clubs interested in the player include Barcelona, Chelsea, Juventus and Paris Saint-Germain, however Jose Mourinho is confident of persuading Pjanic to join him at Old Trafford.
Would he be a good signing for United?
