He was born as Gjergji Kone[2] in Tirana, Albania,[3] and migrated to Greece with his parents Isaac, a biologist, and Leontina, a piano teacher,[4] and older brother to Athens when he was two years old.

Although in times he showed football brilliance, the facts that he was rather unstable and the lack of teamwork could not secure him a firm place in Iraklis' starting eleven.

[12] In July 2010, Kone made an attempt to play for a club outside the Greek borders, signing with Brescia Calcio ahead of the 2010–11 Serie B season.

He put in some impressive performances, catching the eye of club management with his technical training, fast pace and strong sense of goal.

Kone initially arrived at Bologna on a temporary basis as a replacement for the recently departed Francesco Della Rocca, who had moved to Palermo.

The Greek attacking midfielder has made his name in Italy with some truly spectacular goals, notably a scissor-kick volley against Napoli last season at the Stadio San Paolo which gave his side all three points in a 2–3 away victory.

After the defeat, 300 Bologna fans surrounded the squad and prevented them from reaching manager Davide Ballardini, instead screaming for contracts to be torn up over a cordon of riot police.

[21][22] Following the demotion, reports in Italy suggested that Palermo were keen to sign Kone, hoping to close the deal before the 2014 FIFA World Cup.

During extra time, Kone also threatened to score the winner when pouncing on a Miguel Britos error, forcing goalkeeper Mariano Andújar into a save at full stretch.

We are a group full of young kids, I make compliments to the coach as he read the game and for the changes it made because it allowed us to play better in a difficult moment.

"[28] On 23 August 2015, in the opening match of the 2015–16 Serie A season, Kone, as a substitute, helped Udinese stop Juventus' 47-game unbeaten streak at home in the league by providing an assist to teammate Cyril Théréau in an eventual 0–1 away win.

Slowly proved to coach Giuseppe Iachini that he reached on a good physical level and has given greater awareness in their own ability.

However the fans appreciated his entrance against Empoli in the tactical aspect, as he helped the club stopping being anxious and hasty in control of the race and the team seemed more compact.

[43] After his loan, Kone has returned to Udinese, but the administration of AEK is still expecting experienced Greek international attacking midfielder to be released from the Italian club.

[45] On 31 January 2019, Kone became the first signing for new A-League side Western United FC ahead of their inaugural season in a 2-year marquee deal.

Shortly after signing for Brescia, new Greece coach Fernando Santos called him up for UEFA Euro 2012 qualifying matches against Georgia and Croatia.

[50] On 15 June 2015, Kone, as a Greek player, sparked controversy after a photograph surfaced showed him just one day after Greece's humiliating 1–2 defeat to the Faroe Islands making an Albanian gesture, putting him under scrutiny.

[51] On 11 October 2015, Kone scored in a dramatic 4–3 win over Hungary for UEFA Euro 2016 qualifying, meeting a José Holebas cross to net a powerful header.
