Steve McManaman says Liverpool striker Christian Benteke is struggling to make an impact because his movement is poor.
Former Liverpool winger McManaman was highly critical of the Belgium international, who has scored just seven times in 25 appearances this season.
More worryingly the 25-year-old has failed to score and even make an impression in the FA Cup third round games against Exeter.
Goals from Joe Allen, Sheyi Ojo and Joao Teixeira handed Liverpool a 3-0 replay win at Anfield on Wednesday, but Benteke was well below par against the League Two side and headed over the bar from close range and then rounded the keeper before allowing the ball to run out of play with time running out.
“His movement in and around the danger area isn’t good enough. He was on the periphery today but he should be dominating players like this,” McManaman told BT Sport.
“He should be the star man by a million miles.”
Michael Owen also criticised Liverpool’s £32.5million signing from Aston Villa, who was defended by Jurgen Klopp earlier this week.
“No question about it he’s got a lot of quality but he’s got so many gaps in his game that need working on if he’s going to be a top-class player around these parts,” said Owen.
“That last chance was just typical of what he’s going through at the moment, total lack of confidence.
“The team don’t play to his strengths in many ways and he should be scoring, at least, one or two goals in a game like this – he certainly had the chances.”
