RIO DE JANEIRO, April 10 (Xinhua) -- Chelsea have struck a deal with Atletico Paranaense to sign Brazilian starlet Nathan, local media reported on Friday.

The 19-year-old is expected to travel to London next week for a medical check and to sign a permanent contract, according to the Terra news portal.

It is understood Chelsea have agreed to a seven million-euro fee for the midfielder.

Nathan has been capped 20 times for Brazil's under-20 team and made 14 first-team appearances for Atletico last year.

He has caught Chelsea's eye with his performances in a No. 10 role behind the striker but has also been deployed on the left and right of midfield.

Nathan would be the fifth Brazilian in Jose Mourinho's squad, joining Oscar, Filipe Luis, Ramires and Willian.
