Juventus coach Antonio Conte has left the Serie A club after having his contract terminated by mutual consent.
The shock decision was announced on the clubs website on Tuesday, with the 44-year-old departing having steered the Turin club to three consecutive league titles.
It is thought Conte had become disillusioned with the club's failure to invest in a side capable of an assault on the UEFA Champions League, having re-established themselves as the dominant force in Italian football over the past few seasons. Conte is believed to have been angered by the clubs hierarchy who seem willing to sanction the sale of one of the club's star players.
Chile midfielder Arturo Vidal has been strongly linked with a move to Manchester United whilst Juventus bosses were rumoured to be keen on sparking a bidding war between the likes of Manchester City, Chelsea and Paris Saint-Germain for the services of France midfielder Paul Pogba.
Is this the end of Juventus reign as Italy's dominant force?
Juventus eased their way to a third consecutive title last season, finishing 17 points clear of nearest challengers Roma who returned to the upper regions of Italian football after a disappointing few seasons for the capital club. Despite their return to Champions League football, the Rome club are yet to really invest the funds that come with playing in Europe's premier club competition.
They have acquired a number of free transfer players, notably ex-England international Ashley Cole and Dutch midfielder Urby Emanuelson. Whilst Roma should continue their renaissance under Rudi Garcia, it remains to be seen whether they have the capabilities to close the gap on the defending champions.
Napoli, under Rafa Benitez, have remained quiet in the transfer market thus far. After spending heavily last summer on the likes of Gonzalo Higuain, Dries Mertens and Jose Callejon, this summer's budget remains unknown. Benitez has been linked with moves for his former Liverpool players Daniel Agger and Lucas Leiva, both of whom would be welcome additions.
Keeping hold of their star players has been Napoli's struggle in recent seasons, with the departures of Ezequiel Lavezzi and Edinson Cavani to oil-rich Paris Saint-Germain. Benitez will be hoping Luis Suarez's move to Barcelona puts to bed rumours of their interest in Higuain.
The two Milan clubs
Historically two of Europe's most glamorous clubs, the Milan sides have struggled badly in recent times. Inter continue their slow building process back to the summit of European football.
Having been crowned European champions in 2010 under Jose Mourinho they have finished a disappointing sixth, ninth and fifth in the past three seasons. The notable addition of former United captain Nemanja Vidic will strengthen significantly, with the slower tempo likely of Italian football likely to prolong the 32-year-old's ability to compete at the highest level.
Yann M'Vila, once heralded as the new Patrick Vieira has arrived on a season-long loan from Rubin Kazan, with manager Walter Mazzarri challenged with the task of realising the French midfielder's undoubted potential. AC meanwhile have strengthened well, the arrivals of Paris Saint-Germain duo Jeremy Menez and former Chelsea defender Alex on free transfers add both quality and experience to their ranks.
The doubt surrounding the future of Mario Balotelli remains an issue that needs to be sorted.
Trouble in Turin
Juventus remain the outstanding team in Serie A, but the devastation of the popular figure in Conte remains to be seen. Whether players will also feel disillusioned with the board's reluctance to significantly strengthen and become unsettled is yet to be discovered.
New manager, former AC Milan boss Massimo Allegri, will inherit a team full of quality. Whether he can keep that core together and even improve upon iit, time will tell. The race for the 2015 Serie A has truly been shaken up.
