Luis has been outstanding during his loan spell with the Cruz de Malta, but is due to return to Lisbon in four months time.
”I’m calm, whether I renew or not. If it depended on me, I will do everything to stay, but it depends on Vasco and Benfica,” the 26-year-old told Globoesporte.
Luis returned to training on Tuesday after spending three months on the sidelines with a broken foot.
