Finally free of injury and flourishing, the Slovakia international has made a lightning start to the 2018/19 campaign. bundesliga.com puts Duda in the spotlight.
1) Bayern beware!
The Bundesliga has seen this season why Hertha coach Pal Dardai says, "Duda can do things with the ball that very few here can". Bayern Munich & Co. must have been thankful they were not on the receiving end of the Slovakia international's masterclass against Schalke on Matchday 2 when his brilliant free-kick followed up his opening goal. "I think it's the first time in my whole career I've scored twice in a game," he said.

It wasn't the first time he had found the net in a Bundesliga game though. In the first match after Carlo Ancelotti's removal as Bayern coach early in the 2017/18 season, the record champions were cruising at 2-0 up until Duda tapped in from close range to spark a revival that earned Hertha a point. "I'm proud to have scored against Bayern," said Duda. "Perhaps that goal will be my breakthrough at Hertha." Not quite yet, Ondrej…
The Czechs had a 'Little Mozart' in former Borussia Dortmund and Arsenal talent Tomas Rosicky, their neighbours have — according to Dardai himself — "a little artist", but life in Berlin was not always painted in such bright colours for Duda.
After he joined the club from Legia Warsaw on a five-year deal in 2016, he could not have been more bedevilled by injury if the knee and muscle problems that limited him to just 67 minutes in his first season had had horns and a trident.
And when he was fit again in summer 2017, he wasn't match fit, at least not by Dardai's demanding standards. The former Hungary international came down hard on his midfielder, pressing him into extra training and punishing him with push-ups when Duda did not meet his expectations. It worked.
"I haven't seen him like that in training for a long time," the Hertha boss said by January 2018. "His fleet of foot and dynamism are better than they have been recently. Perhaps we'll play with him as a number 10." He did, and as Salomon Kalou said after Duda's Matchday 2 special in Gelsenkirchen, "Number 10 is back".
3) First steps
The talent that has the Bundesliga all gooey-eyed was first shown in eastern Slovakia where Duda played for his hometown club, MFK Snina, before joining one-time UEFA Champions League group stage participants Kosice.
After bursting into the first-team aged 17 under Jan Kozak — the man who would eventually hand him his Slovakia debut too — Duda impressed enough to win the Peter Dubovsky prize in 2014, the honour named after the late former Real Madrid player, awarded to Slovakia's best young player, and also seen on the mantelpieces of Marek Hamsik, Martin Skrtel and Stanislav Lobotka.

In February, 2014, Legia came along and whisked him across the Tatra mountains to the Polish capital, not that it fazed young Ondrej. "Absolutely not. Ondrej is a clever lad," insisted his father and agent, Ondrej Sr. "Going from Kosice where 200,000 live to Warsaw with ten times as many people has not changed him at all. He can handle that pressure."
4) Stone cold
The winner's medals earned through central roles in two Polish titles and two national cup wins, including a domestic double in his final season before joining Hertha, are testament to Duda's coolness under pressure.
A heavyweight list of clubs that included AC Milan, Inter Milan, Napoli, Hannover, Cologne, Arsenal, Spurs and Everton were also impressed, fluttering their eyelashes longingly at the then-Legia midfielder, whose performances were drawing favourable comparisons with those of his hero, former Liverpool and England midfielder Steven Gerrard.
He was not only a target for rival clubs, but also opposing fans. A stone thrown by supporters of Albanian side KF Kukësi in Legia's Europa League qualifier in July 2015 hit Duda in the head. Blood streaming from the wound, the Slovak was stretchered off and the game abandoned.
5) Super Slovak
A warmer welcome is assured for Duda when he returns to his native country. One of a promising generation that includes Celta Vigo's Lobotka, the midfielder replaced Hamsik against Lukas Hradecky's Finland in November 2014 to make his senior international debut and struck his maiden goal — the matchwinner — against neighbours the Czech Republic the following March. At UEFA EURO 2016, he became the first Slovak to score at a European championship in the 2-1 group-stage defeat to Wales.
"Hertha did a really good thing in getting him," said Duda's club and international teammate Peter Pekarik, who had been asked particularly about Ondrej's character by Hertha sporting director Michael Preetz before the Bundesliga side made their move.
"He's a great guy who has a good head on him. He knows what he wants and he definitely has a great future ahead of him."
