(CNN) -- What makes a classic tennis final?
There are many elements that can combine to make a final live long in the memory of those who watched it, as well as played in it.
Perhaps, against all the odds, a player has turned the match around -- snatching victory from the jaws of defeat to win in dramatic fashion.
Or both players are involved in a ding-dong battle for supremacy -- the lead changing hands numerous times, leaving the crowd on the edge of their seats.
Does a final merit its place as a classic if one player produces play of such supreme skill that they comfortably defeat the other?
Or conversely, perhaps the length of time on court, regardless of the quality of play, gives a match added reverence.
Maybe the weather has played its part, lengthy rain delays adding to the suspense and changing the course of proceedings.
Sometimes there is a "Clash of the Titans," struggle -- two players at the top of their games slugging it out to the best of their ability -- or a previous rivalry, be it through country allegiances or past matches between the players.
Either way, for those lucky enough to be at court side to witness these epic battles, they will never be forgotten.
