This year for Murray has been quite similar to Djokovic's year last year. Both won 2 Masters titles (Murray can still add to his tally in Paris next week). Also, they both beat the players ranked 1, 2 and 3 over the course of the season (although Djokovic managed to beat all three in one tournament last year). And they both reached the final of the US Open.
The only real difference is that Murray has been less consistent in the Grand Slams. Djokovic reached threee SFs and a final last year, while Murray has been less consistent, but has improved as the year has gone on.
It will be interesting to see whether Murray can keep this kind of form going and then push on and acheive what Djokovic has this year, in 2009.
