IF Kaizer Chiefs are able to clinch the league and cup double by beating SuperSport United in the Nedbank Cup final in Durban on Saturday, they will extend yet another of their records in local football.

Chiefs are looking to complete the prestigious achievement for the sixth time, but for the first time in 21 years.

Winning the league championship plus the country's national cup is regarded worldwide as the ultimate achievement for a club in a single season.

Chiefs' last double came in a dominant 1992 season where they took three trophies. Amakhosi started that season by winning the BP Top Eight; sacked coach Franky Mbale; replaced him with Jeff Butler; went on to complete a treble with a 2-1 extra-time win over Jomo Cosmos in the Bob Save Super Bowl final; and edged out Hellenic to the league title.

Chiefs could have won a fourth trophy in the 1992 season but lost to Clive Barker's AmaZulu in a thrilling Coca-Cola Cup final.

Chiefs also had double successes in 1977, 1979, 1981 and 1984. Their five previous doubles eclipse three for their arch-rivals Orlando Pirates and one each for Cape Town Spurs and Sundowns.

Pirates were the last club to do the double just two years ago, that coming after a 13-year gap. Before that, the last side to do it was Mamelodi Sundowns, who won the league by five points from Chiefs in 1998 and beat Pirates on penalties in a replay in the Bob Save Super Bowl final.

Sundowns could have won a third trophy but lost to Chiefs on penalties in the Rothmans Cup final.

Chiefs are the only side to have won four trophies in a single season, which they achieved under Scottish coach Joe Frickleton in 1984.

Meanwhile, Chiefs coach Stuart Baxter says his players are exhausted.

"They are very, very tired and if they are going to play important national team games, we've all got to be careful with them."

Eight Chiefs players were named by national coach Gordon Igesund last Friday in his Bafana Bafana squad for the two World Cup qualifiers against Central African Republic and Ethiopia away on June 8 and June 16, preceded by the friendly in Lesotho on June 1.
