He was mocked at the start – not least because some of his quotes in Italian were lost in translation – but Calzona’s spell has so far been successful.
In Euro 2024 qualifying, Slovakia suffered only two narrow defeats against Portugal, and were otherwise convincing. Calzona has managed to implement a clear tactical change.
Previously at big tournaments, as in their 0-0 draw against England at Euro 2016, Slovakia relied on a packed defence with counter-attacks, which were not too systematic.
However, Calzona set out to create a playing style that would suit the best Slovak players. He relies on a variation of 4-3-3 which works well especially because of the variability of the midfielders.
Stanislav Lobotka is a defensive midfielder who is also great at passing as well as breaking through the lines and being aware of what is going on around him. Juraj Kucka plays as a box-to-box midfielder while Duda, seen as Hamsik’s successor, adds creativity.
Slovakia have become more open and adventurous, these days usually trying to play out from the back.
That works perfectly for Lobotka who, during the build-up, can also shift in between the two centre-backs, Denis Vavro and Milan Skriniar. Both are comfortable with ball at their feet, while adding solidity.
Left-back David Hancko is also a player to look out for.
He plays as a centre-back for Feyenoord but starts on the left for the national team and his strength lies in supporting the attack.
Slovakia have started to play with a higher defensive line, trying to press right up the pitch.
Calzona believes in an attacking style and managed to convince the players of his methods while creating a strong bond with them.
In February, he accepted an offer from his former club Napoli to coach them until the end of the season.
The Slovak FA agreed with this caretaker role, and Calzona signed a new contract with the national team until the end of 2025.
