Chelsea have reportedly beaten Manchester City to the signature of Brazilian wonderkid Nathan, with his signing reportedly set to be announced on Wednesday.

The 19-year-old midfielder, who is believed to be the next big name in South American football, was pursued by the Citizens two years ago when Nathan impressed during the 2013 FIFA U-17 World Cup held in the United Arab Emirates.

However, Brazilian side Atletico Paranaense had refused to sell the promising midfielder and City were forced to look somewhere else.

Although Nathan has managed to break into Atletico Paranaense's first team, he is expected to leave this summer due to him having a serious contract dispute with the Brazilian side.

City reignited their interest in the youngster, but Chelsea have reportedly beaten the Citizens to his signature as the Brazilian youngster, who was given permission by his current club to fly to London to discuss a potential move to Stamford Bridge, has already passed a medical at Stamford Bridge after holding successful talks with the Blues this week.

And now, according to the Daily Mail, the Blues are on the verge of officially announcing the signing of Nathan for a reported transfer fee of £4.5 million.

Meanwhile, tickets for Chelsea's crucial Premier League clash against London rivals at the Emirates are reportedly being sold at exorbitant prices upto £950 per ticket.

Although the tickets for this game, scheduled to take place on 26 April, are officially sold out, they are reportedly being sold online on exchange websites.

Tickets at the Emirates for big matches such as this one normally cost up to £97 (the most expensive in the Premier League) on the official website.

However, one website is reportedly selling the Arsenal-Chelsea game tickets at ridiculous rates, with the highest tickets in the away and home fans section being £950 and £712.50 respectively, according to the BBC.

Although the demand for the tickets to the Arsenal-Chelsea game is pretty high at the moment, it is expected to drop if the Blues manage to beat Manchester United this weekend.
