Football fans may not be too familiar with the NFL’s draft system.In short, clubs take it in turns to pick players to sign. It's very different to how transfers work in football.But what if the sport was to adopt an American style draft? What would the top 10 picks in world football be?Well, David Jones put that task to Jamie Carragher and Gary Neville this morning on the Sky Football Show.The draft is supposed to last five years - so there is an absence of older players like Cristiano Ronaldo.So who did Carragher and Neville pick?Let’s take a look:

CARRAGHER'S TOP 10 DRAFT PICKS

Explaining his picks, Carragher said: “Mbappe is very close to being the best player in the world - I think that’s going to happen in the next two or three years so I certainly think he’ll be No.1. His ability, his pace and obviously his age as well.

On picking Messi, Carragher said: “This draft is over five years so it’s not the best 10 players, it’s a draft system for the next five years so a lot of my players are a good age to go on over the next five years to be the best players in the world. Yes, Messi, I know he’s 33 but I just think he’s that good. For years we’ve been saying maybe he’s not the same or he’s not running about everywhere but he can still score goals when he’s walking around the pitch. So I’ve got no problem picking Messi for the next couple of years.

NEVILLE'S TOP 10 DRAFT PICKS

Neville’s list featured a few slightly different names - although he did also have Mbappe as No.1.

But perhaps more interestingly, he included five Liverpool players - more than Carragher did.

But Neville defended his decision by saying: “I think the Liverpool team at the moment is the best in our league and the best in Europe obviously last season and came so close the year before so I don’t think it’s that big of a surprise really.”

Carragher questioned Neville on whether he thought the likes of Mohamed Salah and Sadio Mane could keep up their incredible performance level into their thirties, to which Neville replied: “Well you obviously don’t!”

At the end of the day, it was a little fun exercise for Carragher and Neville to keep them busy for a few minutes in the absence of proper football - but it was one they clearly disagreed on.
