Former tennis star Andre Agassi has admitted the lion mane-style hairstyle he sported during the 1990s was actually a wig, in extracts from his autobiography published in British weekend newspapers.

Agassi said he wore a hairpiece held together with pins in his first Grand Slam final, the 1990 French Open final, and blamed his concerns that it would fall apart for losing the match to Andres Gomez.

Before the match he prayed "not for victory, but that my hairpiece would not fall off", he writes in "Open".
