Andy Murray faces Novak Djokovic for the third time in 2012 on Sunday in the Miami Masters.
Rafael Nadal withdrew from his semi-final with the Scot due to his troublesome knee injury, giving Murray a bye to the final.
Spaniard Nadal just pulled out two hours before the scheduled start, and said: "I take no pleasure from this but I cannot go on court and lie to everybody."
Murray has won five out of his 12 encounters with Djokovic, but has never beaten him in a Grand Slam tournament. He lost to the Serb most recently at the Australian Open semi-final stage during an epic five-set match.
Murray and Nadal's 39-shot rally:
He did however defeat the world number one at the same round of the Dubai Championships in early March, and beat Djokovic in the final of the Miami Masters in 2009.
Britain's number one has dropped just one set in Miami - against Djokovic's compatriot Janko Tipsarevic in the quarter-finals.
So ahead of two of tennis' finest clashing, here's the best of their past clashes...

Dubai Championships, 2012
On the five occasions Murray has beaten Djokovic, he has won in straight sets, with the exception of Cincinnati last year, when Djokovic retired hurt 3-0 down in the second set. Here's Murray's latest win against the "Djoker" less than a month ago.
