Liverpool midfielder Lucas claims Chelsea defender David Luiz must change his game to avoid being labelled a Premier League flop.

The pair are teammates for Brazil but Lucas got the better of Luiz at the weekend. Sky Sports pundit Gary Neville said Luiz looked like he was a PlayStation footballer being controlled by a 10-year-old.

Lucas said: "We know he has a lot of potential and everyone can see he likes to go forward and is trying to adapt.

"In English football, if you go forward and leave space behind, then it can be crucial for the other team.

"If you are attacking, then you have to think about what would happen if you lose the ball.

''But he is a fantastic player and will learn."
