Portuguesa midfielder Guilherme is another top target, having impressed this season in Serie B, but it is Corinthians supporting Luisão who has shot to the top of the priority list.
Offered to PSG for €10 million in the summer, Corinthians hope to get a deal in the €6-8million range, from where they can look to find some sponsors to aid the purchase.
The centre-back, now 30, has 42 caps for Brazil, but has not played in his homeland since departing for Benfica over eight years ago now. He could be ready for a triumphant January return.
