Liverpool star Kostas Tsimikas lost his concentration at a pivotal moment for the Reds in France on Thursday.
The Premier League side were dealt a blow, losing 3-2 to Toulouse in the Europa League.
During a controversial game that was marred by VAR controversy, Steve McManaman singled out Tsimikas for rebuke.
He told TNT Sports: It was poor from Tsimikas, just fell asleep and allowed the opposition to get into the game.
Caiomhin Kelleher has no chance with the deflection, flies off Jarell Quansah's leg into the net.
A very unlikely lead for the home side, and not a good look at all from the Liverpool left-back.
Really disappointing play."
