Carlos Aguair has been sacked as Atletico Madrid B coach.
A terrible run of six defeats and one draw has left the club's reserve side in the relegation positions for a drop to the Tercera, Spain's fourth tier.
Atleti B play in the Segunda B, in the same group as Zinedine Zidane's Real Madrid Castilla side.
Atleti will now name the third coach of the side this season, after Óscar Mena resigned in the opening week.
