At his time at the club, however, Lazović found it difficult to break into the first team squad at Feyenoord and moved onto Bayer Leverkusen in the summer of 2005 on a loan deal.

He had a decent half-season at his old club, scoring five league goals, but various reports continued about his apparent disruptive dressing room influence.

Lazović was a member of the squad that beat Ajax 4–2, as he scored for himself and set up two goals for Mads Junker and Youssouf Hersi respectively.

Lazović attracted the attention of PSV early on,[9] before moving to them at the end of the season for €6.6 million, signing a five-year deal.

After setting up a goal for Ibrahim Afellay against Ajax, he appeared to allegedly insult Stevens, and after the match (which PSV lost 4–1) he was fined for showing dissent.

On 11 November 2009, he earned a hat-trick and set up goals for Ola Toivonen (twice) and Otman Bakkal in a 5–1 win over ADO Den Haag.

[14][15] After the deal, PSV general director Jan Reker said, "Danko Lazović told us about the interest of Zenit about a week ago.

"[16] Lazović made his Russian Premier League debut for Zenit on 13 March 2010 against Krylia Sovetov Samara, coming on as a substitute in the 54th minute for Konstantin Zyryanov.

[17] Two weeks later, Lazović made his first impact on the scoresheet, delivering a perfect ball to set up Danny for the first goal against Dynamo Moscow.

[18] On 14 November 2010, he scored the Championship-winning goal against Rostov in the 40th minute, helping Zenit win its second Russian Premier League title in four years.

On 19 June 2011, during a 2–0 win over Volga, Lazović made headlines when he was tasered by the police with an electric baton after he tried to throw his shirt into the stands, that left a burn mark under his right shoulder blade.

[19] Afterwards, he was quoted by Sport Express newspaper as saying, "I simply went to give my shirt to the fans after the game when a policeman appeared behind me and hit me in the back with an electric shock, I don't know why this happened.

[22] Also, Lazović first team opportunities would soon be limited due to goalscoring form striker Aleksandr Kerzhakov and several new signing, leading him to be placed in the reserves.

[28] After leaving Zenit Saint Petersburg, Lazović returned to Serbia to rejoin Partizan on a free transfer, signing a two-year deal.

Lazović played his first match in the 2014–15 season against HB on 15 July 2014, in the second qualifying round of the 2014–15 UEFA Champions League, where he scored a brace and provided an assist in a 3–0 home win.

[39] Lazović made his international debut for the Yugoslavia national team on 27 March 2002, in a friendly match against Brazil in Fortaleza.

In June 2010, he was selected in Serbia's squad for the 2010 FIFA World Cup, [40] where he appeared in group stage matches against Germany and Australia.

In March 2011, two weeks before a crucial Euro 2012 qualifier against Northern Ireland, Lazović decided to retire from the national team at the age of 27, choosing to focus on his club Zenit.
