Highly rated Brazilian Danilo arrived at Portuguese champions Porto on Wednesday, with fans eagerly anticipating his debut after his 13 million euro ($16.8m) transfer from Santos last July.
The 20-year-old, a member of the Brazil side that won the World Under-20 title last year, is the second most costly transfer in Portuguese football history after his compatriot and new team-mate Hulk, who joined Porto for 19 million euros in 2008.
Danilo, who is primarily a midfielder but can also play at right-back, signed a five-year contract with Porto but Santos got agreement from the Portuguese side that he could stay until the winter transfer window.
During that time he helped Santos win the Libertadores Cup.
"As with every team with whom I have played, my target is to win trophies," he told the club website.
