Manchester United are considering Newcastle midfielder Sandro Tonali as a replacement for Casemiro, who is expected to leave the club next summer, reports The Telegraph.
The Italian midfielder is one of Manchester United's top transfer targets. In addition to Tonali, United are also interested in Nottingham Forest's Elliot Anderson and Crystal Palace's Adam Wharton.
Newcastle are reportedly set to demand around £100m for Tonali, with Casemiro recently stating that this season will be his last at Manchester United.
