Brazilian teenager Nathan has arrived in London for a medical ahead of a summer move to Chelsea, according to reports.
The 19-year-old midfielder only made his debut for current side Atletico Paranaense last year, and has featured in just a further 10 games for the club.
However, Chelsea are ready to pay £4.7m to secure his services, and could wrap up the deal in the next few days, reports The Metro.
Nathan has also been linked with a move to Manchester City, who have reportedly been tracking the youngster since he featured in the World Under-17 Championships two years ago.
