Liverpool owner John W Henry has reaffirmed his opinion that Roy Hodgson's squad lacks depth.
Liverpool appointed Spurs' former director of football Damien Comolli this week to help and Henry believes the Frenchman will help the team achieve their goal.
"We're not deep enough. We don't have enough youth," he told Sky Sports News.
"If you look at Manchester United and Arsenal they have depth. They have relative young teams and that's something that he (Comolli) can help us with."
Some believe the addition of Comolli could undermine Hodgson's authority, but Henry insists the former Fulham boss wanted the position filling.
When asked if Comolli's arrival would undermine Hodgson, Henry replied: "No, not at all.
"When I first met with Roy it was really clear that he wanted someone in that position, so I really didn't talk that much with Roy over the week or so before we made the decision to bring Damien in.
"So I think he may have been surprised when I brought it up, but he's fully supportive. He knows Damien.
"I think the model really requires people of certain personalities for it to work and Roy and Damien are two personalities that will mesh well together.
"It will be a group decision. You build consensus. I think it's a very good model, but though each will be in charge of their own areas.
"We're still building a team. We're in the middle of building that. We may make some mistakes early on, but we're going to try and avoid that and we're studying every day."
