BUENOS AIRES, Jan. 11 (Xinhua) -- Marcelo Gallardo has cast doubt over his future as head coach of River Plate as the Argentine giants prepare for the second leg of their Copa Libertadores semifinal against Palmeiras.
The 44-year-old's contract expires in December, but he admitted he could leave earlier.
"After the Copa Libertadores, we will undertake a detailed analysis and see if I have reasons to continue or not," Gallardo told a virtual press conference on Monday.
"At the end of the month, we'll discuss it. We have to wait a little longer."
Palmeiras enter Tuesday's clash in Sao Paulo as overwhelming favorites to progress to the final after winning last week's first leg in Buenos Aires 3-0.
On Saturday, River crashed out of the Diego Maradona Cup with a 2-0 home loss to Independiente.
Gallardo has guided Los Millonarios to 11 titles - including two Copa Libertadores triumphs - since taking charge of the club in 2014.
