Novak Djkovic said on Wednesday he is aiming to carry his superb form into the Davis Cup and winning the competition with Serbia this week is one of his "greatest goals". The 36-year-old great has won three Grand Slams this year, with an all-time best tally of 24 and clinched his seventh ATP Finals title on Sunday in Turin, beating both Jannik Sinner and Carlos Alcaraz. Djokovic and Serbia, who last won the Davis Cup in 2010, face Great Britain on Thursday in the last eight. "It's the last week of the season, so one final push is necessary from each one of us," world number one Djokovic told reporters.
