The report states that the futures of David de Gea, Anders Lindegaard, Victor Valdes and Sam Johnstone are all unresolved.
Da Gea has been heavily linked with a move to Real Madrid while Victor Valdes, Anders Lindegaard and Sam Johnstone all want out after failing to break into the starting line-up.
The Daily Star goes onto say that the Netherlands international keeper Jasper Cillessen is also on United’s radar.
The Metro reported that the Red Devils are preparing to launch a £24.5 million bid to sign Galatasaray’s Muslera.
Galatasaray want to keep hold of Muslera but could be forced into considering such a substantial offer.
Muslera played a key role in the Lions winning the league for a record 20th time last season and earning the right to wear a fourth star – Galatasaray also won the double for a record sixth time.
The experienced keeper has won three league titles at the Lions and also the Copa America with Uruguay.
