Now only a 24th straight win will bring the golden end to his remarkable season, and although former British No 1 Rusedski admits it will be hard, he feels Murray will find a way to lift himself for the final. Murray was thrilled to come through against Raonic in the longest match ever at the season-ending tournament It was an absolutely brilliant that third set from Murray in the way he digs deep and finds a way to get the job done, Rusedski told Sky Sports.He breaks another record - 23 matches in a row. Its hard enough doing 10 in a row, but 23 and also against the very best players on the planet. I mean, Raonic was exceptional, he really raised his game.But now Murray must show that belief, that desire to come through. He wants to be year-end number one and we have the dream final possibly happening tomorrow.

Hes got 24 hours to get ready, but he will be so motivated. I was so impressed - that was one of his greatest performances ever to come through that in three hours and 38 minutes because he had to be tired in that third set.Mentally it is going to be tough for him because hes going to be sore, hes going to be tired and hes got to find a way to lift himself. This is where the experience of coach Ivan Lendl comes in, who has been through these situations before. Murray pulled off this magnificent half volley during the second set tie-break Murray has now played two three-hour monster matches and will be back on court on Sunday evening and Fleming thinks its asking a lot.As usual Andy seems to come up with his best responses when his back is against the wall and it most certainly is now, said former doubles specialist Fleming.Lets face it, hell need to come out quickly and establish himself and hopefully ride the wave.
