Whilst it wasn't a shock that Inter Milan finally sacked manager Walter Mazzarri on Friday, his replacement has caused a real stir over in Italy.
The ink was barely dry on Mazzarri's P45 before Inter president Erick Thohir announced that the new man at the helm would be Roberto Mancini.
Mancini, 49, left Galatasaray in the summer due to a disagreement with the board of the Turkish giants, and has made a shock emotional return to the San Siro.
Mancini spent four successful years in charge of the Nerazzurri between 2004 and 2008, but resigned after speculation suggested he would be sacked in order for Jose Mourinho to replace him.
That did of course happen in the end, but Mancini left the club having won three league titles, two Italian Cups and two Italian Super Cups before his acrimonious exit.
Having eventually pitched up at Manchester City, Mancini continued to win silverware, winning the league title, FA Cup and Community Shield in his three-and-a-half years spell at the Etihad Stadium.
Mancini spent heavily at City, and reports suggest that he could look to bring three of his signings with him to the San Siro - before even taking charge of a game.
Serbian centre back Matija Nastasic is at the top of the list according to the Daily Star, with the former Fiorentina star down the pecking order at City.
The 21-year-old looked like a star in the making under Mancini, but has fallen out of favour under Manuel Pellegrini at City, and could be had for just £5m - a bargain for Mancini and Inter, particularly considering the struggles of Nastasic's compatriot Nemanja Vidic this season, whilst his knowledge of Serie A could come in handy.
Another former Serie A star - and Serbian international - has been linked, as Aleksandar Kolarov has also been touted as a target. A £16m addition from Lazio under Mancini, Kolarov is underrated but the recent displays of Gael Clichy could leave him on the sidelines, and Mancini may look for his experience over the youth of Inter left back Dodo.
Finally, striker Edin Dzeko - snapped up for £27m by Mancini - hasn't quite got going yet this season, and could be a prime target for Inter given that Rodrigo Palacio and Pablo Daniel Osvaldo have combined for just four goals so far this season.
City will surely move on from Nastasic in January and a move to Inter makes total sense, whilst City could be tempted into selling Kolarov if the price is right and if they find a suitable replacement.
However, keeping Dzeko is paramount for City. He offers them a focal point in attack whilst he's on the pitch, and with Stevan Jovetic regularly injured and Alvaro Negredo out on loan at Valencia, keeping the Bosnian is a must for City - even if he hasn't hit the ground running this term.
