Borini returns to the club where he spent a productive loan spell during the 2013/14 season.
Borini has returned to the club where he spent a productive loan spell in the 2013/14 season, and turned down a permanent move to the Stadium of Light only last season - with a deal finally going through on Monday.
Last season, Borini's opportunities with the side were limited and he only managed to find the net on one occasion as he slipped down the pecking order, with Brendan Rodgers leaving him out of the Reds' pre-season tour to the Far East and Australia to train with the reserves this summer as the writing was put on the wall for the Italian.
In his Liverpool Echo column, Aldridge wrote: "It's a good move for both him and Liverpool.
"He doesn't want to be training with reserves and we've got good money for him, especially when you think what we bought him for.
"It's for his own good. He doesn't want to be festering, he wants to play, he's still a young lad so good luck to him."
Borini had a successful time of things at the Stadium of Light during his season on loan at Wearside - giving the fans a few memorable moments as he helped the side avoid relegation out of the Premier League, as well as scoring goals during their run to the League Cup final that year.
It will be interesting to see if he can have a similar effect on the side this term and whether he can endear himself to the supporters in the same way he did a couple of seasons ago.
