The clubs have agreed a fee, but it appears that Borini wants to keep his options open.
Borini's time in English football has been well documented. After brief spells at Chelsea and Swansea City, he moved to Roma and had a relatively successful time of things in Serie A.
Brendan Rodgers decided to bring the forward back to England when he signed him for Liverpool shortly after being appointed manager at Anfield in the summer of 2012.
He struggled to make an impact in his first season, which was partly down to some terrible luck with injuries which denied him a chance to string a run of games together in order for fans to see the best of the Italian. It's one of the reasons he only has two goals to his name for Liverpool.
But at Sunderland he did get the opportunity to have regular game time and put a string of performances together. Though some will say that his scoring record still isn't the greatest at the Black Cats having scored 10 goals from 40 appearances, there were flashes of what he brings to a side.
A cool head in some pressure situations, good movement and a good eye for goal. But the difference is at Sunderland he was given the opportunity to get a decent run of games under his belt. His spectacular strike when he came off the bench against Newcastle United may have gone a long way to helping him get that, but he was afforded time to impress and build his confidence.
His attitude of wanting to stay and fight for his place at Anfield is a commendable one. In a side that scored 101 goals last season, he knows the expectation on him to deliver, even as squad player, in the season ahead is going to big.
Even if Liverpool are playing in more games in the season ahead and he gets a bit more game time, one feels it isn't going to be too regular. It looks like Daniel Sturridge is going to be the main man up front for Liverpool, and possibly the incoming Loic Remy playing alongside him.
At Sunderland, it looks as though he'll be amongst the regular starters, and it would be more of an opportunity for him to show his best form. Purely from a playing point of view, one would think that would be the best decision for the Italian. At the age of 23, he is still developing as a footballer and could become a valuable asset to any team if he is given the game time to develop.
It's a big decision for Borini, but maybe more assurances of guaranteed playing time could the best one for his career.
