The Merseyside giants announced the news via their official Twitter account on Monday afternoon as Borini re-joins the club he played for on-loan during the 2013-14 campaign.

The 24-year-old was manager Brendan Rodgers’ first signing when he was appointed in the summer of 2012, but he failed to establish himself in the team during his debut season after scoring just one league goal in a injury-hit campaign.
His spell at the Stadium of Light in the following season proved to be more fruitful as he played a huge part in their survival in the division as he found the back of the net seven times in 32 appearances.
Borini returned to Anfield last summer but found himself further down in the pecking order behind the likes of Daniel Sturridge, Mario Balotelli and Rickie Lambert.
With Rodgers bolstering his attacking options with the signings of Christian Benteke and Danny Ings this summer, Borini clearly had no future at the club and joins the Black Cats on a permanent basis.
