United eye youngster to shore up defence.
Manchester United face competition from Inter Milan in the pursuit of highly promising FC Basel defender Fabian Schar, according to Fichajes.com.
The Swiss international, 22, is one of the most highly regarded young defenders in Europe at the moment and has been linked with several top clubs in recent times.
The likes of Arsenal and Barcelona have tracked Schar in the past, but now United are stepping up their interest as they seek to improve at the back this January.
Louis van Gaal invested heavily in attacking players in the summer, but could do with more in defence after Nemanja Vidic and Rio Ferdinand both left the club at the end of last season.
