"San Lorenzo de Almagro have a new coach. The club agreed this afternoon to hire Ricardo Daniel Caruso Lombardi and he will take charge of the professional squad on Wednesday," they said on their website on Tuesday.
The 10-times champions, nicknamed the Saints, Crows or Cyclone, are in the bottom four of the relegation standings, which are calculated on points averages over three seasons.
San Lorenzo, one of Argentina's so-called Big Five clubs, face a play-off against one of the top four teams in the Primera B Nacional, the second division, in June. If they drop into the bottom two they will automatically go down, as they did in 1981.
"I think the main thing is to make your players heroes, take the pressure off them," the stocky, quick-talking 50-year-old, who sports a goatee, told Fox Sports.
It will be his second stint at one of the 'Big Five' having successfully avoided relegation in 2009 at Racing Club, his rivals in his first match in charge on Sunday and also struggling for form.
Madelon resigned after Sunday's game against Velez Sarsfield behind closed doors after their Nuevo Gasometro stadium was suspended for crowd violence.
In the latest incident two weekends ago, for which supporters were banned from Sunday's match, fans tried to storm the match officials' changing room angry that referee Diego Abal allowed visiting Colon's controversial equaliser in a 1-1 draw, a decision he admitted the following day had been a mistake.
Caruso Lombardi spent more than a decade coaching in the lower divisions of the Argentine league before taking charge of first division Argentinos Juniors in 2007. He has also coached Newell's Old Boys and Tigre.
