Borini spent last season on loan at the Stadium of Light and played a key role in their Premier League survival bid and their run to the League Cup final.
The Italian had a habit of scoring important goals for the Black Cats. He scored home and away against Newcastle United, the crucial penalty in the win against Chelsea at Stamford Bridge as well as pivotal goals during their League Cup run, including the opening goal in the final itself.
A fee of £14 million has been agreed with Liverpool, though the 23-year-old is said to be keen on fighting for his place at Anfield. However, Larsson has said it would be a big deal for Sunderland if Borini were to head to the Stadium of Light on a permanent basis.
He's quoted in the Northern Echo, saying: "Fabio was here last year and did really well, so he knows the place and we know him. Of course that would be a great signing, but it’s for the people behind the scenes to deal with and we’ll have to see if it gets over the line.
“He showed last year just what a good player he is. Especially in the second half of the season, he showed what he can do for the club. We all know what he can bring to the team, and you need as many good players as you can to help improve the competition in the squad. If Fabio returns, it will help everyone else drive on and get better.”
Sunderland fans certainly seemed to take Borini to their hearts, and in his first season at Anfield he didn't really seem to settle given the lack of impact he made combined with injury problems.
His attitude of wanting to fight for a place at Anfield is one to admire given they are bringing in reinforcements, and Daniel Sturridge is likely to be the main striker for the Reds. It is unlikely he would be the first choice forward.
An interesting line from Larsson is that Borini helps drive everyone else on within the team. Not only could that be in terms of competition for places, but the Italian does seem to have a big personality and has a big effect on the dressing room.
He seemed to enjoy his time at Sunderland, and those at the Stadium of Light seem incredibly keen on seeing him back at the club for the long-term.
