Josko Gvardiol rose to global prominence as ‘the man in the mask’ at the 2022 World Cup but had long since been destined for the top.

The Zagreb-born 21-year-old caught the eye in Qatar, but more for his unruffled dynamism at the heart of Croatia’s defence than for the black face mask worn to protect his broken nose.

Gvardiol, who on Saturday completed a £77.6million to Manchester City, was a stand-out player during Croatia’s run to the semi-finals and emerged as arguably the best young player at the tournament and certainly among the world’s best left-footed central defenders.

Argentina’s Enzo Fernandez received FIFA’s young player award, but Gvardiol was included in a five-man shortlist alongside the likes of Jude Bellingham and Morocco’s Azzedine Ounahi.

Dozens of British media outlets named him in their team of the tournament.

His career had already been on a steep upward curve after making his debut for Dinamo Zagreb aged 17 in 2019 and less than a year later he joined RB Leipzig for £13.8million.

Leipzig loaned Gvardiol straight back to Zagreb for the remainder of the 2020-21 season and he played a key role in his hometown club’s domestic double-winning campaign.

The Bundesliga club beat a host of European clubs to the teenager’s signature, including Leeds, who had offered a reported £19million under then head coach Marcelo Bielsa.

Gvardiol later revealed that he had been close to teaming up with Bielsa, who had regularly phoned him personally to convince him of his project at Elland Road.

But he opted for Leipzig and, in his first season at the Red Bull Arena, Gvardiol won rave reviews, helping them lift the DFB Pokal – their first major trophy – and qualify for the Champions League after finishing runners-up to champions Bayern Munich.

Leipzig also reached the 2022 Europa League semi-finals – they lost 3-2 on aggregate to Rangers – and, with Gvardiol integral to their success, Europe’s big guns moved in.

Chelsea’s reported offer of £77.5m in the summer of 2022 was rejected as Leipzig extended the Croatian’s contract until 2027 and he continued to impress.

He scored his first Champions League goal as Leipzig halted Real Madrid’s 16-game unbeaten start last season in a 3-2 win before the World Cup break, heading the German side into an early lead.

Croatia head coach Zlatko Dalic had no doubts Gvardiol was on the path to stardom when handing the then-19-year-old his first senior international start in their opening group defeat to England at Euro 2020.

Gvardiol started in every game at the Euros as Croatia lost to Spain in the round of 16 and Dalic’s admiration grew at the World Cup in Qatar.

Lionel Messi duped Gvardiol when setting up Julian Alvarez for Argentina’s third goal in Croatia’s 3-0 semi-final defeat, but that did not detract from the 6ft 1in defender’s immense contribution overall.

After Croatia reached the knockout stages in Qatar, Dalic said: “Gvardiol is the best central defender in the world. He’s so mature. The way he plays, with the grace he controls the ball – it’s amazing.”

Manchester City will be hoping Gvardiol can live up to such high praise.
