Around 26,600 people will fill the converted La Cartuja Olympic stadium in the southern city of Seville on each day of the December 3 to 5 final after organisers decided to sell extra tickets, reports Reuters.

"(Organisers) have finally decided to expand capacity to include new areas of the stadium, after checking that visibility from those zones was adequate," the Spanish Tennis Federation said on its website.

The current record of 25,578 spectators dates back to the 1954 final between Australia and the United States in Sydney, according to the United States Tennis Association (USTA).

A specially constructed, covered clay court has been built for the match inside a stadium generally used for athletics and soccer, which staged the 2003 UEFA Cup final between Porto and Celtic.

Around 1,000 people are working on the event, which has a budget of six million euros ($7.99million), the federation said.
