09/04/2014 Newsround

Good Wednesday morning to you. I'm Nel and this is Newsround coming up.

A new track for Chris Hoy. And... Chelsea players celebrate a dramatic

win with a selfie. This is Newsround. First up, he's

only eight months old but Prince George has had his first royal

engagement in New Zealand. The prince, along with his parents, met

new mothers and fathers in Wellington. George met some other

babies the same age as him and even had a little play. The visit is part

of his parents three week tour of New Zealand and Australia. Ahead of

this summer's World Cup, children from around the world have met in

Brazil to join forces and tackle a problem facing disadvantaged kids.

Some of them are in care and some are actually living on the streets.

But they all played together in the Street Kids' World Cup, to learn

more about each other's lives and send a clear message to world

leaders that no child should have to live on the streets. Former CBBC and

Blue Peter star Andy Akinwolere is in Brazil working with the project,

and he sent us this report. It's thought that about 100 million

children around the world live on the streets. Most of these children

boys ages ten to 14, and they are especially vulnerable to danger.

Many governments choose to ignore this problem, so I'm in Brazil at a

football tournament to find out more. 230 kids, 19 countries, boys

and girls all with one goal. No child should ever have to live on

the streets. She is a child just like mine or yours. But a child

who's had very different opportunities to the children we

know and love. As a result, has been disadvantaged from early on in life.

Once my mum, step dad and sister became homeless, I was living with

my father. We were moving so many places for a long time. It was

really hard to get through all the stress of moving around places and

not knowing what to do with yourself. Just trying to get through

everything. The United Nations wants governments to come together and

address the rights of homeless children across the world, by

providing shelters to offer safety, education and health care. But, more

importantly, the love and care these children deserve. It feels great to

be in Brazil playing football, it's a nice opportunity. We've trained a

lot and are finally here. We have a lot in common. We are all in care,

we've moved through things in our past. We are strong people to get

the rid and have a future ahead of us. Sir Chris Hoy has announced he

is swapping two wheels for four. The Olympic gold medallist has retired

from cycling but is taking up sports car racing. Next year, he will drive

for Nissan in the British GT Championship and his ultimate dream

is to compete in the 24 hour Le Mans race in 2016. Next, check out these

selfies posted by Chelsea's David Luiz moments after last night's

dramatic win on an away goal against Paris St-Germain in the Champions

League quarter final. Substitute Andre Schurrla made it 1-0 in the

first half, but it was this goal in the 86th minute by Demba Ba that

sealed the victory. Sparking an amazing touchline celebration from

Blues boss Jose Mourinho, although he says he wasn't enjoying the

moment. No, it was not to celebrate. It was to tell the players how we

have two play the last ten minutes. Because I know in that moment they

want to celebrate. They want to think that the game is over. I have

to tell them what we have to do in the last seven or eight minutes. It

was not a celebration. But you could see that. And Manchester United

manager David Moyes will be hoping his team can follow Chelsea into the

semifinals. They face Bayern Munich tonight and go into the match 1-1 on

aggregate, and David Moyes will be hoping striker Wayne Rooney will be

fit enough to start for the Reds. Very cute animal news now, and we

finally have a name for a pair of polar cubs who were born at a zoo in

Germany last year! The male cub is called Nobby and his sister is

called Nela. All animals born at the German zoo in 2013 have been given

names beginning with "N", and so these twins are no exception. That's

all from me, Newsround's back right here in about half an hour.
