On 16 January, Serbia water polo team beat Spain 8–5 in an excellent first game at the start of the European Championship. This was a match between two great rivals who played in the finals at the World Championships in Rome. On 17 January, Serbian water polo players as expected got the second triumph. "The Dolphins" selection won against Germany with a score 13–12 in a very hard match. Pijetlović was the man who made the difference scoring four goals for his team including the final for 13–11 which got Serbia the victory. On 19 January Serbs defeated the defending European champions Croatia with 15–12 in a third round game and made a decisive step towards direct placement in the semifinals. Udovičić was the top scorer for his team with three goals. This was a big and hard clash for bouth nations in which Serbs came out as winners. The clash will be also remembered for unsportsmanlike conduct of Dobud who struck Filipović from behind who instantly got the bruising under his eye. On 21 January, Serbia routinely came to the fourth victory at the European Championships in Eindhoven beating Romania 14–5. After the Montenegro and Spain 10–10 tie and Germans 10–9 victory over Croatia, Serbia has qualified for the semifinals. On 23 January, in the last round of group A where Milan Aleksić played his 100th official match for Serbia national team, Serbia lost to Montenegro with 11–7. In a match that in principle didn't mean much to Serbia, it was clear that the absence of motive may be crucial for the final result. On 27 January Serbia defeated the current world champion, Italy, with 12–8 and thus qualified for the finals. It was not revenge for defeat in the final of 2011 Shanghai, it was a simple lesson, which consisted of three phases – solid defense, a wise selection of moves in the attack and forceful implementation. On 29 January Serbia water polo team won its second European title since independence, and "dolphins" won the gold by beating Montenegro 9–8, paying them back for defeat in the 2008 European Championship finals played in Malaga.
Serbia defended their title in the 2014 Championship held in Budapest 14–27 July 2014. After a bad start in the group, having lost to Hungary 6–8 and tied with Croatia 8–8, they secured the second place by defeating Spain 8–6. After a routine victory over Greece in the quarterfinals, the semifinal match with Montenegro was an uphill struggle: Serbia came from behind after losing 5–1 in the second quarter, to win by 10–9 in the end and meet Hungary in the finals. By contrast, the domestic team had an easy path to the finals, having scored all victories thus far. However, in the finals they succumbed to the expectations and got crushed by increasingly self-confident Serbian team, who led by 7–2 by the halftime and securely brought the match to an end, with the final score of 12–7.Gojko Pijetlović was elected the best goalkeeper of the tournament.
On 25 December 2011, Serbia's water polo team was included in a humanitarian action "Bitka za Bebe" ("the Battle for the Babies") playing an exhibition match with the team of the Faculty of Organizational Scihences (FON), in Belgrade.
