David Luiz urges Diego Costa to join PSG
Luiz added that PSG sign only the best player and Costa would be a welcome addition
"Diego is one of the clinical strikers in Europe and would be a welcome addition to any team," Efe quoted Luiz as saying on Tuesday.
"I think PSG have made their intent clear over the last three or four seasons -- that we only add the best players," added the Brazilian, who joined the French team in June 2014 from Chelsea for 50 million pounds sterling ($71 million).
Costa, 27, the top scorer of the Blues this year, has been linked in recent months with a return to Atletico Madrid, the club he left in 2014 for London.
"If Diego decides he has had enough of England and wants a new challenge he would be welcome here. Diego and myself have had our clashes," said Luiz.
"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," acknowledged the Brazilian defender.
