The Liverpool striker struggled again in the FA Cup this week.
The Belgian has struggled at Anfield since a big money move from Aston Vila, with a series of unimpressive displays so far.
That continued this week, with a disappointing performance in the midweek win over Exeter City in the FA Cup.
It seems that Benteke does not fit into the style of Jurgen Klopp’s side, with him struggling to adapt to the high intensity game the German demands of his team.
Cascarino though, says that the major flaw is the striker’s lack of movement in games and that is costing him opportunities in the area.
“There's one major flaw, I believe," he told Sky Sports News HQ.
"He's got this awful habit of standing alongside centre-halves which you cannot do. You have to move, create space for yourself to try and get opportunities.
"He's got so many good attributes - he's a physically quick, technically gifted player, but unless he starts moving...”
While Cascarino claims that Benteke’s lack of movement is the major flaw for him so far, the striker is likely to say his side’s style is also to blame.
The Belgian’s strength is arguably in the air, with him often profiting against defenders when the ball is put into the box and on his chest.
Liverpool’s style is in stark contrast to that though, with them preferring to get the ball down and play a passing system, which does not suit Benteke’s style.
So while his lack of effort could be criticised, he may suggest that a change in his team’s play when he is in the side would help him to flourish.
