Fabio Borini's move to Sunderland has stalled after the Italian forward travelled with Liverpool on the club's pre-season to the United States.
The 23 year old spent last season on loan at the Stadium of Light but manager Gus Poyet claims the two clubs have agreed a fee over a permanent move this summer.
Borini featured for Liverpool in the friendly win over Preston before jetting out to the United States, where they will faces Roma, Olympiakos and Manchester City across three pre-season games.
Following Sunderland's 5-1 win over Darlington, Sunderland boss Poyet said of the rumoured 314m deal: "What I can inform you is that we have agreed terms with Liverpool.
"It's an ongoing thing. We've done the steps that we needed to do properly, but the next step is that we are still waiting for the correspondence. Then we will go on from there, doing everything official, in the right way.
"I think Fabio's impact is clear, as is the reason why we want to spend that quantity of money. We know how much he can give us because we know him perfectly. It would be perfect for us.
"I'm really calm regarding Fabio and Marcos because as everyone knows, it's not about numbers or quantity; it's more about the quality of your signings. I'm delighted with what we've done so far."
Liverpool manager Brendan Rodgers has confirmed Sunderland have an agreement but that talks are ongoing: "He spent a really successful period with Sunderland last year, and it's obviously a fantastic club.
"They've offered to buy Fabio and that's where it's at. There is an agreement between the clubs, but nothing is agreed with the player as of yet. So he's still very much a Liverpool player, but when that changes, I'm sure you'll be among the first to know."
While reports are suggesting Borini is being evasive over committing himself to a move to Sunderland, where he scored seven goals in 25 Premier League starts to help the club avoid relegation, Liverpool could themselves be holding up the deal.
Loic Remy is understood to be flying into the Reds' Los Angeles base to complete his move from Queens Park Rangers, while Belgium international Divock Origi has reportedly agreed to join the Anfield club.
