Manchester United are reportedly poised to sign Brazilian youngster Dodo in a move that has stirred up controversy.

The 17-year-old centre-back currently plies his trade with Corinthians and is regarded as an extremely exciting prospect for the future.

Dodo has been quoted as saying that he expects to join the Red Devils over the summer in a transfer that would see him link up with compatriots Rafael and Fabio da Silva and Rodrigo Possebon.

United have yet to indicate whether they will swoop for Dodo but the thought of such a move has angered 1970 World Cup winner Carlos Alberto.

Alberto finds it infuriating that big European clubs are able to sign Brazilian youngsters and has called on FIFA to change its laws.

"It is disgraceful United are allowed to do this to Brazilian football," Alberto said in the Manchester Evening News.

"The big teams have the money and can take our best players. It is a big problem in Brazil.

"The clubs cannot keep good young players because they can make much more money in other countries. They should change the law so, at least until the age of 20 or 21, the best players play in Brazil and get experience before moving to Europe.

"FIFA must do something."

Manchester United have accepted a bid from Hull City for England Under-21 striker Fraizer Campbell.

Hull have been given permission to discuss personal terms with Campbell after agreeing a reported £6m fee.

Campbell, 21, scored 15 goals to help Phil Brown's to promotion in 2008 during a successful loan spell at the KC Stadium during the 2007/08 season.

He spent last season on loan at Tottenham as part of the deal that took Dimitar Berbatov to Old Trafford.

Brown was keen to sign Campbell after Hull were promoted but missed out when the player joined Spurs.

Campbell, who has seven Under-21 caps, started just one Premier League game during his time in north London and only made one brief appearance in the final three months of the campaign.

A number of clubs have reportedly shown an interest in signing him this summer.

Wigan have received bids in excess of £16million from Manchester United and Real Madrid for Antonio Valencia, according to Sky Sports News.

The Ecuadorian winger has long been linked with the two European giants and it is now reported that the pair have tabled bids.

United are searching for creativity on the right after big-money signing Nani has failed to live up to expectations and Valencia is said to have impressed boss Sir Alex Ferguson.

Real are desperate to overthrow Spanish and continental champions Barcelona and the 23-year-old was thought to be close to a move in the winter transfer window.

A switch failed to materialise, but it is now understood that newly-elected president Florentino Perez, who has pledged a return to the dazzling days of star signings from his first spell at the Bernabeu, is ready to test Wigan's resolve.

Valencia joined Wigan in 2006 in a loan move from Recreativo de Huelva and the deal was made permanent in January 2008.

The Latics are currently without a manager following Steve Bruce's move to Sunderland, but Roberto Martinez is expected to be unveiled as successor on Wednesday

Sir Alex Ferguson has joined the chase for Sheffield United's £7million-rated whizz-kid Kyle Naughton.

Manchester United manager Fergie had brilliant young right-back Naughton watched in the Blades' 1-0 Championship Play-Off Final defeat by Burnley at Wembley 13 days ago.

And the 20-year-old Sheffield-born starlet did not disappoint.

A source revealed: "Sir Alex has kept tabs on Naughton, but was keen to see how he'd handle the big stage at Wembley.

"The reports he got were very positive. Kyle wasn't fazed and relished the occasion. He came out of the final as United's outstanding performer."

Blades boss Kevin Blackwell is waiting to see if his £1m bid for 22-year-old Southampton midfielder Andrew Surman has been accepted.

Lyon president Jean-Michel Aulas last night opened the door for Manchester United to make a £30million move for striker Karim Benzema.

Sir Alex Ferguson will be looking for a forward if Carlos Tevez rejects United’s offer to turn his loan move into a permanent deal.

Ferguson has kept tabs on highly-rated Benzema, above, for more than two years, having dinner with Aulas after one Lyon match.

Aulas said “Karim said he wants to stay. I don’t want to sell. So he’s here at 99 per cent.

“However, Kaka should not be leaving Milan and he will join Real Madrid. We have entered spiral madness. I am relaxed. I will not say Karim is untransferable.”

Benzema, who scored a penalty for France in their 1-0 win over Turkey last night, said: “If there is a huge offer and the chairman says I have to go, I would probably leave.

“But I will not go and see him and ask to leave. I am 21 years old and I will have time to play for another club.

“The clubs will carry on calling. Everyone is looking for forwards. But I am fine at Lyon.”

Tevez should inform United of his decision after Argentina’s World Cup qualifier next Wednesday, with Manchester City set to pounce if he decides to move on.
