The Fifa president, Sepp Blatter, says the world governing body needs his style of "continuous evolution" rather than the "revolution" proposed by rival candidate Mohamed Bin Hammam.
Blatter and Bin Hammam are going head-to-head for the top job in elections in June, with the incumbent seeking another term after taking over Fifa in 1998.
"I have all the motivation, experience, ideas and energy necessary to complete my mission," Blatter wrote in a letter to all 208 Fifa member associations.
"We do not need revolution within Fifa, but the continuous evolution and improvement of our game and our organisation. In these challenging times, Fifa needs first stability, continuity and reliability."Reuse content
