Leonardo Bonucci has completed his move to Milan, becoming the 10th man to play for them, Inter and Juventus.
The three clubs are the most historically successful in Italy, taking over 60 per cent of Scudetti between them.
That has understandably created an intense rivalry across Milan and down the A4 to Turin, so there aren’t many men who have played for all three clubs.
However, Bonucci isn’t the first player to have worn the shirt of all three, and he joins some illustrious names.
Here are the nine other players who have been Bianconero, Nerazzurro and Rossonero.
Andrea Pirlo [Inter 1998-2001, Milan 2001-11, Juventus 2011-15]
Pirlo grew up supporting Inter, so it was a dream come true for the midfielder when he joined the Nerazzurri from Brescia in 1998.
The young Pirlo failed to break into the side however, making just 22 Serie A appearances for the Beneamata in three seasons, which included a loan spell at Reggina.
Inter opted to sell the midfielder across San Siro for €17m, a cost to the Rossoneri which was partially offset by the transfer of Dražen Brnčić in the opposite direction.
Playing in a deeper regista role, Pirlo became one of the best midfielders in the world with Milan, winning two Scudetti and two Champions League titles.
However, after 10 seasons with the Diavolo, he failed to agree a new contract and moved to Juventus on a free transfer.
Gianluigi Buffon has described the move as perhaps the greatest bargain of all time, and l'architetto was pivotal as the Old Lady regained her Serie A crown.
Dictating the play from the heart of midfield, Pirlo won four Scudetti and the Coppa Italia before moving to New York City FC in MLS.
Edgar Davids [Milan 1996-97, Juventus 1997-2004, Inter 2004-05]
A tough-tackling midfielder, Davids’ dreadlocks and goggles were an instantly recognisable part of Marcello Lippi’s Juventus juggernaut.
The Dutchman’s first experience in Italy was actually with Milan, for whom he signed in 1996 after back-to-back Champions League finals with Ajax.
His 18 months with the Rossoneri yielded just 19 League appearances though, and Davids moved to Turin in January 1997.
He would go on to win three Scudetti at Stadio delle Alpi, making over 200 appearances.
After a brief loan spell with Barcelona, Davids spent the 2004-05 season with Inter and made 19 appearances.
Zlatan Ibrahimovic [Juventus 2004-06, Inter 2006-09, Milan 2010-12]
The famously nomadic striker has won the Scudetto with all three sides, although the two won in Turin were later revoked in the Calciopoli scandal.
After joining Juve for €16m from Ajax, Ibrahimovic became a key part of Fabio Capello’s side, often at the expense of fan favourite Alessandro Del Piero.
The Swede scored 26 goals in 92 games, but - by his own admission - forced a move to Inter when the Bianconeri were relegated to Serie B.
Ibra’s goals fired the Nerazzurri to the Scudetto in each of the following three seasons, before a €70m move to Barcelona.
An increasingly fractious relationship with Pep Guardiola saw Ibrahimovic return to Italy a year later, joining Milan on a season-long loan.
After 21 goals in 41 games fired Max Allegri’s side to the title, Ibrahimovic signed permanently in 2011 but his 28 Serie A goals weren’t enough to stop Juventus taking the Scudetto.
In a mirror image of his Juve departure, the Swede was sold to Paris Saint-Germain against his wishes for a €20m fee.
Roberto Baggio [Juventus 1990-95, Milan 1995-97, Inter 1998-2000]
The Divine Ponytail’s transfer to Juve caused riots among Fiorentina fans, but his 115 goals in 200 games helped the Old Lady to a Scudetto, a Coppa Italia and the UEFA Cup.
The emergence of a young Del Piero saw Juve push Baggio out, and he won the Scudetto with Milan in 1995-96.
After a poor second season, the forward had a renaissance at Bologna, scoring 22 goals in 30 Serie A games and earning a place in the Italy squad for the World Cup.
Two seasons at Inter followed, before Baggio ended his career with four seasons at Brescia.
Christian Vieri [Juventus 1996-97, Inter 1999-2005, Milan 2005-06]
Vieri scored 14 goals in 37 games for Juventus during the 1996-97 season, helping his side win the Scudetto.
He was sold to Atletico Madrid that summer, but after 24 goals in 24 La Liga games he returned to Italy with Lazio. After another successful season, Vieri made the move to Inter for a then world record fee of €49m.
While he was prolific in his six seasons with the Nerazzurri, Vieri’s efforts brought just one Coppa Italia in 2005 and he moved to Milan for the 2005-06 season.
By then he was a bit part player, scoring once in eight Serie A games.
Aldo Serena [Inter 1978-79, 81-82, 83-84, 87-91, Milan 1982-83, 1991-93, Juventus 1985-87]
With four spells with Inter and two with Milan, Serena takes the prize as the man who has moved between the three clubs on the most occasions.
After a Scudetto with Inter and Juve, he won the title back-to-back with Fabio Capello’s Milan.
Serena was Capocannoniere with Inter as they took the Scudetto in 1989, and also won the UEFA Cup with the Nerazzurri.
Enrico Candiani [Inter 1937-46, Juventus 1946-47, Milan 1949-50]
Candiani played close to 200 Serie A games for Inter, winning the Coppa Italia in 1939 and the Scudetto in 1940. After leaving the Nerazzurri he scored 15 goals in 35 games during one season with Juventus, before a two-year spell with Pro Patria.
That was followed by one season with Milan, before Candiani wound his career down at Livorno and Foggia.
Patrick Vieira [Milan 1995-96, Juventus 2005-06, Inter 2006-10]
Despite playing for all three of the country’s most successful clubs, Italy may not have seen the best of Patrick Vieira.
The Frenchman played just twice for Milan after signing from Cannes in January 1996, before moving to Arsenal for £3.5m.
After establishing himself as one of the world’s best midfielders during nine seasons at Highbury, the World Cup winner joined Juventus in 2005.
A groin injury affected his performances in Turin, and the Scudetto won in that season was stripped in the Calciopoli scandal.
Four seasons with Inter followed, but Vieira never managed to make more than 20 Serie A appearances, although he did win four Scudetti.
Giuseppe Meazza [Inter 1927-40, 46-47, Milan 1940-42, Juventus 1942-43]
Meazza is such a legend that the official name of San Siro is Stadio Giuseppe Meazza.
His 241 goals in 348 games fired Inter to three Scudetti, before 37 games for Milan.
Meazza then spent a season at Juventus, before returning to Inter via Varese and Atalanta.
One of the first great Italian players, Meazza also scored 33 goals in his 53 Italy caps, winning the World Cup in 1934 and 1938.
