Manchester United are believed to be closing in on the signing of Benfica's Renato Sanches.

Multiple news outlets are reporting that Benfica president Luis Filipe Vieira arrived in Manchester on Thursday to finalise the £46million transfer.

According to the Daily Mail, 18-year-old Portuguese ace Sanches will cost United an up-front fee of £31m, with a further £15m to be paid in add-ons.

Sanches' agent, Jorge Mendes, has also been spotted in Manchester this week adding further fuel to the fire that a deal is set to be completed.

The box-to-box midfielder is rated as the most promising player from his country since Cristiano Ronaldo and is expected to sign a long-term deal with the Red Devils in the coming days.
