Gerrard believes the Dutch forward failed to make an impact during the match at Molineux and argued that the lack of urgency from the bench is unacceptable.
"He has to start Ngumoha now," Gerrard told TNT Sports. "He’s coming on and he’s doing more in a short cameo... than Gakpo’s doing in 65, 70 minutes." The former captain noted Liverpool looked "desperate" and "poor" for long periods.
