The Brazilian admires Diego Costa and wants him to return to Atletico Madrid. He is convinced that the 27-year-old could be again one of the world's best player, if he returns.
Both left Atletico in 2014 for Stamford Bridge, but Luis returned just one year later to Spain.
Filipe told 'Marca':
"Costa is the player who gave me the most advice in my career, and I love him like a brother. We both know that our mutual love for Atletico is a common theme in our relationship. I have no doubts that he would be very happy here at Atletico.
"He has been the best No.9 in the world and can be the best again depending on what he does at his club.
"I always want him on my team, so hopefully I can get back to playing with him".
