They do things a bit differently in Italy.
Whereas in the Premier League, any player who moves from one club to a rival is considered a traitor, and can enjoy seeing their jerseys burned by the more ridiculous football fans on social media.. In Serie A it's not that big a deal.
It is not uncommon for a striker to be playing up front for the team you support that shattered your heart in a local derby years or even months ago. There's not much animosity when it comes to negotiations, if you're not playing, best of luck somewhere else.
The players just want to keep playing regularly at a high level, but we've picked out a few that have moved clubs enough to make Robbie Keane jealous.
Marco Borriello
Played for: Treviso, AC Milan, Empoli, Reggina, Sampdoria, Genoa, Roma, Juventus, Carpi, Atalanta, Cagliari.
Having signed for Cagliari in the summer, Marco the explorer has kept his quest to play for every top-flight Italian team in existance. Sadly for him, time is not on his side at age 34. Otherwise we would fully expect him to do it.
Roma were the only team with which he made more than 50 appearances, but he score more goals in less games for Milan.
Alessandro Matri
Played for: AC Milan, Cagliari, Juventus, Fiorentina, Genoa, Lazio, Sassuolo.
Yet to play for Sassuolo after being loaned out to four Italian clubs in two years, Matri is seemingly damaged goods as nobody wants to give him regular football.
And yet he played 125 times for Cagliari before featuring 69 times for Juve, maybe he just likes living out of hotels?
Fabio Quagliarella
Played for: Torino, Fiorentina, Ascoli, Sampdoria, Udinese, Napoli, Juventus.
Now at Sampdoria for the second time after he left his boyhood club Torino, which he signed for from their bitter rivals Juventus, despite starting his career at Torino... Quagliarella tends to mess the people of Turin about.
And funnily enough it's Udinese for which he played the most games, 73, with Napoli and Sampdoria also getting goals out of him before his most notable period at Juve.
He really got around.
Hernan Crespo
Played for: Parma, Lazio, Inter, AC Milan, Genoa.
The man with the least amount of clubs on this list Hernan Crespo qualifies because he played such prominent and memorable roles with each club.
He really had a history and rapport with the fans, which is kind of surprisingly giving the inevitability that he would soon play for the team you hate.
Iconic at both Parma, Lazio, and AC Milan back when Serie A ran Europe, he finished his career at Parma where he became a coach and went down with the ship, so his loyalty there can't really be questioned.
Alberto Gilardino
Played for: Verona, Parma, AC Milan, Fiorentina, Genoa, Bologna, Palermo, Empoli.
Easily best know for his time at Fiorentina, Gilardino is one of those names you never stop occasionally hearing about from Italy despite not seeing him play much after 2012.
A trip to China will do that, as he needed a break from clubhopping at home, but now he's back and still going strong at 34.
Christian Vieri
Played for: Torino, Atalanta, Juventus, Lazio, Inter, AC Milan, Sampdoria*, Fiorentina.
Apologies for the oddly unsettling photo.
Christian Vieri was one of the most feared strikers in Europe at Inter where he bagged 103 goals in 146 games, but after leaving the club in 2005 to make way for the future of football; Adriano, Vieri never found stability again in his career.
Inter is probably the only Italian club where he is revered, as his spells at Juve, AC, Lazio, and Fiorentina were not as spectacular.
Giampaolo Pazzini
Played for: Atalanta, Fiorentina, Sampdoria, Inter, AC Milan, Hellas Verona.
Pazzini to his credit has managed to feature consistently wherever he has played, but crossed the Milan divide without second thought after one season at Inter where he played a staggering 50 games.
Fiorentina was his longest run at one club, and having signed for Hellas Verona at the start of last season we can't rule out him joining another club as he's only 32.
Antonio Cassano
Played for: Bari, Roma, Sampdoria, AC Milan, Inter, Parma.
An absolute madman with a spark of genius always waiting to strike, Cassano was notorious in his pomp and is the owner of some of the crazier stories in football.
Roma will always be the first club assosciated with him, but he also featured prominently for Sampdoria and Parma before they ceased to exist for a while there.
