Who is Lucas Leiva? What is his true position? And based on a previous article about South American youngsters leaving too early, eg. Gabriel Paletta, is Lucas ready to come to the Premiership just yet?
Mark Williams, Leamington Spa (and many others)
These moves are always a gamble, but I think this is a good one.
He's an exciting player of a type that Brazilian football hasn't produced too many of recently. Of late their central midfielders have tended to be 'holders' who sit and allow the full-backs to push forward.
Lucas is different. He's a big, blonde figure whose power and physical strength comes with attacking ability.
He can pass well and loves to rumble forward. He gets on the scoresheet both with blistering shots from range and from bursting beyond the strikers.
You can certainly imagine him playing alongside Javier Mascherano, for example.
I don't have the same fears for him as I did with Paletta. He's had two full seasons behind him - one helping Gremio win promotion from the second division, and then last year's success when he was chosen as the player of the championship.
In a perfect world you might want him to stay another year before moving on, but (a) Gremio need to sell to balance the books and (b) with Liverpool's strength in depth in central midfield it looks as if his first campaign will be a bedding in season.
