Russia's world number five Nikolay Davydenko believes he needs to adjust his game and find something extra if he is to challenge the world's top tennis players next season.
The 27-year-old crashed to a 6-1 7-5 defeat to world number three Novak Djokovic in the Masters Cup final in Shanghai last night.
He's one of the most consistent players on the ATP Tour but is not satisfied with a top five finish for the fourth straight year.
Davydenko is one of the hardest working players in tennis and this week's Masters Cup was the 22nd tour event he played this year, not to mention three Davis Cup ties and the Olympics.
But apart from his Miami Masters triumph, where he beat world number one Rafael Nadal in the final, hiss other two titles this year came at relatively minor tournaments in Austria and Poland.
