Roma coach Rudi Garcia is confident Daniele de Rossi will stay at the club following reports Manchester United have made a bid for the midfielder.United are also reportedly interested in Athletic Bilbao midfielder Ander Herrera as Moyes tries to conclude his first major signing. Bilbao president Josu Urrutia claimed on Friday that a firm bid for the 24-year-old had been lodged and immediately dismissed. And Urrutia says the only way Herrera will leave the club is if he demands a move and his release clause - reported to be £30.75m - is met. Speaking at a press conference, reported on Athletic's Twitter feed on Friday, he said: "We have had an offer for Ander Herrera. Our club is different, it is based on sentiment. Our objective isn't to make money. "We received the offer last night and have communicated that we will not negotiate for our players. "For a player to go, first the player must express his desire to leave the club and pay the release clause." Moyes was asked about Herrera at his press conference ahead of Sunday's game against Liverpool, but was not prepared to name United's targets. He said: "We would try not to disclose our bids, if that's possible. We would just let the clubs deal with it and try to do it in the professional manner." Everton midfielder Marouane Fellaini and Barcelona's Cesc Fabregas have also been the subject of bids from the Premier League champions this summer.
