Diego Costa (left) and David Luiz have clashed in previous meetings between each other

David Luiz has urged Chelsea's Diego Costa to join him at Paris Saint-Germain.

The Brazil international, who moved to the French champions from Chelsea for £40m in 2014, believes Costa is one of the world's best strikers and would welcome him to the Parc des Princes.

Luiz and Costa have clashed in previous games against each other, but Luiz insists they always ended with a hug.

He said: "If Diego decides he has had enough of England and wants a new challenge, he would be welcome here.

"Diego is one of the clinical strikers in Europe and would be a welcome addition to any team. I think PSG have made clear their intent over the last three or four seasons - that we only add the best players.

"Diego and myself have had our clashes. On the field he is physical and confrontational - he will get in your face. That is part of his game. But off the field he is one of the nicest guys you can meet."
