Liverpool defender Andrew Robertson slammed Dominik Szoboszlais mistake in the FA Cup win over Barnsley as unacceptable, admitting his side still have room for improvement despite their recent unbeaten run.
Szoboszlai was guilty of a careless blunder when his miscued back-heel inside his own penalty area allowed Barnsleys Adam Phillips to score in Mondays third round tie at Anfield.
Liverpool were leading by two goals at the time of Szoboszlais miscued pass and went on to clinch a 4-1 win against their third-tier opponents.
