Lallana has played very well for club and country but he can't score. Would rather have Mane who you know can score goals and provide the pace and width that Lallana isn't able to offer, happy for Lallana to be a squad player or start in the big games but he doesn't have that spark of quality and end product we need in the regular first XI. The only issue is Mane's consistency, but he was played centrally last season so maybe he is better out wide?
