Catania have formally announced the appointment of Diego Simeone in place of Marco Giampaolo.
The 40-year-old Argentine, formerly of Pisa, Inter and Lazio, will be unveiled later today.
Simeone has signed a contract until June 30, 2012.
La Gazzetta dello Sport understands Catania sacked Giampaolo last night.
Differences with the club's chief executive Pietro Lo Monaco ultimately proved fatal for him.
Catania have won just one of their last seven games, losing five and conceding 16 goals.
