Saints have recovered most of the fee they paid for Manolo Gabbiadini after agreeing to sell the striker to Sampdoria for £12m.
The 27-year-old joined the Saints from Napoli for £14.6m in June 2017 but has been less than prolific, scoring just 12 goals in 60 appearances.
New Saints manager Ralph Hasenhuttl had last week outlined a departure for the striker was likely, while citing a need to trim down his large first-team squad.
That led to talk of a move away from St Mary's, with AC Milan, Fiorentina and Real Betis also believed to have been in the running for Gabbiadini.
After finding his role in the squad restricted, Gabbiadini has sealed a return to Italy and the team he played for from 2013 to 2015, joining in a switch worth in the region of £12m.
"I think with this intensive pressing system we try to play, it is not his way, so it was better to find a solution which is better for both sides", the Austrian said.
Given that Gabbiadini's stock has fallen so far in the intervening period and that he is so clearly unsuited for the high-tempo approach Hasenhuttl wants to bring to the south coast, losing less than £4m on him looks like great financial business.
"He's a fantastic player and I am sure he can score goals at every club in the world and we go in different ways".
"It is better to make it as soon as possible but it's not so easy in the winter transfer period,"n he said".
