Chelsea are reportedly close to completing the signing of Brazilian youngster Nathan, after the playmaker passed his medical with the Blues on Tuesday.

According to the Daily Mail, Jose Mourinho's team are close to signing the Atletico Paranaense midfielder after agreeing a fee of £4.5m ($6.6m) with the Brazilian club.

The 19-year-old midfielder is said to have been in London for the past week for talks after getting permission from the club's president, and will now join the strong contingent of Brazilians, Willian, Oscar, Felipe Luis and Ramires at Stamford Bridge.

Nathan is seen as the next big prospect to come out of Brazil and it is believed that he was spotted at the World U17 Championships two years ago. He has already broken into Atletico Paranaense's first-team, making him a readymade prospect for the Blues.

This news will come as a big blow to Premier League champions Manchester City, who were also tracking the midfielder following the World Championships and could not sign him then, due to his contractual issues with the Brazilian club, which allowed Jose Mourinho to swoop in.

Nathan is a versatile midfielder, who can play in a number of positions, his primary position is as an attacking midfielder, but he can also play on the left of midfield or just behind the main striker, and the report claims that this quality could see him being included in the first-team next season by the Portuguese manager.

Meanwhile, Izzy Brown, a Chelsea youth-team player was delighted when the Blues youngsters won the UEFA Youth League after beating Shakhtar Donetsk 4-2 in the final.

The young midfielder, who has won the FA Youth Cup and the European U17 Championships with England, believes that this win tops it all.

"It's my best feeling yet as a player," Brown said, as quoted on Chelsea's official site.

"I've won the FA Youth Cup and the Under-17 European Championships with England but this just tops it all off. It was an excellent game and I thought we deserved our win. To be on the bench for the first team and then come back here to play has been a great experience for me and I'm just so happy we've won the competition," the English midfielder added.
