By December 2010, Djokovic was coming to the end of his fourth consecutive year of world number three. He stood there, standing behind Federer and Nadal, the most dominant players of the 20th century. By then, Federer had won 16 Grand Slams and Nadal had 9, both of whom had achieved career Grand Slams. By then, Djokovic had already won the 2008 Australian Open, where he defeated Federer in the semi-finals. He also reached two other Grand Slam finals, both at the U.S. Open, first in 2007 and second in 2010, three years later.
2010 was also the year djokovic made major changes in his diet. He removed gluten from his diet and soon felt more energetic and not as prone to fatigue as in previous games. But in the first year of the new decade, there was another major factor that inspired Djokovic. He was a man who was immensely proud of his national identity. Djokovic first participated in the Davis Cup in 2004, and at the age of 16, Djokovic represented Serbia and Montenegro in the Davis Cup, beating Latvia in the second group. By 2010, Serbia was a full member of the World Group, the highest level of the tournament. Throughout 2010, Djokovic was the leader of the team, winning two games in every game.
By December, Serbia reached the final for the first time, against France. Inside the Belgrade Stadium, the spectators were very active and eagerly awaited their players receiving this honour. But it takes a lot of effort — three days of rollercoaster scores. On the first day, Frenchman Monfils beat Tipsalevic 6-1, 7-6 (4) and 6-0. Djokovic beat Simon 6-3, 6-1, 7-5 to equalize serbia. Davis Cup matches are often centered around doubles. This game is the most thrilling. Serbian doubles veteran Zemundzic partnered Trojky to lead the French team of Lodra and Clement in two sets. But the French duo rose to the chase and eventually won the epic match, which lasted 4 hours and 34 minutes, 3-6, 6-7 (3), 6-3, 7-5, 6-4.
In order to win this match, Serbia must win two matches on the last day of December 5, 2010. So the burden fell on Troyki and Laudra. Amid cheers from his team and across the arena, Troyki played brilliantly, winning the tournament 6-2, 6-2, 6-3. "It's unbelievable," Troyki said. "I don't know how to react, what to do. It was the best moment of my life. "While Trojki was the hero in the final, everyone knows that the core and soul of Serbia's victory was Djokovic. Djokovic said: "It was unbelievable today. In this case, it was probably the best game I've played this year. It's definitely a lot of pressure and expectations. ”
The Davis Cup victory proved to be an important catalyst. In 2011, Djokovic won the Australian Open. He dominated the sport all year and won Wimbledon and the U.S. Open. By the end of the 2020 Wimbledon Open, he was tied with Federer and Nadal in Grand Slam tournaments to finish first in history with 20 Grand Slam titles.
