Manchester United target Bruno Fernandes will face Benfica in Friday's Lisbon derby "unless disaster strikes", says Sporting Lisbon boss Silas, reports BBC Sport.

United and Sporting have held face-to-face talks over the transfer of £60m-rated Portugal midfielder but there has been no agreement between the clubs over a fee.

"The only certainty I have is that Bruno Fernandes will be present against Benfica," said Silas.

"When we have such an athlete it is normal for a lot of teams to want him, but tomorrow he will be there unless disaster strikes."
