Manchester United manager David Moyes is hoping he can finally make some major additions to his squad as he looks to try and seal deals for Roma midfielder Daniele De Rossi and Athletic Bilbao star Ander Herrera.

Bilbao have already rejected one bid for the 24-year-old and yesterday confirmed that they will only consider an offer if Herrera's release clause is met.

"Our club is different, in that it is based on feeling," said Bilbao president Josu Urrutia. "Our objective is not to make money.

"We received the offer last night, and we communicated [to the club in question] that we do not negotiate for our players. If a player is to leave, first he has to inform us that he wants to go and then his release clause has to be met."

The Telegraph reports that Manchester United are now prepared to meet Herrera's release clause of £30.7m as Moyes attempts to land a midfielder who can improve his side.

United were frustrated when numerous bids for Barcelona midfielder Cesc Fabregas were rejected, while another target, Thiago Alcantara, eventually sealed a move to Bayern Munich. With Everton refusing to allow Marouane Fellaini to leave, it seems attention has now moved to Herrera.

Herrera is yet to earn a senior cap for Spain but has repeatedly featured at youth level and impressed for Bilbao when United played them in the Europa League two seasons ago.

With the transfer window closing on Monday evening it seems Moyes is determined to make sure the move goes through.

Triggering his release clause means United will only have to discuss personal terms with the player, and the chance to compete in the Champions League may be a deciding factor for Herrera.

Landing Roma's star midfielder De Rossi is likely to be tougher, however. The 30-year-old was believed to be keen to leave Roma at the end of last season but has since been convinced to stay by new manager Rudi Garcia.

The Telegraph believes that United will test the Italian club's resolve by bidding around £10m, but it will be difficult to convince Garcia to allow his captain to leave the club.
