:00:00. > :00:00.Good morning. Leah here with your morning Newsround, with news of
:00:07. > :00:12.Liverpool's agony as their Premier League hopes slipped away last
:00:13. > :00:14.night. We will be heading in a tunnel deep undersea for a birthday
:00:15. > :00:18.celebration. And if you thought snooker was
:00:19. > :00:22.boring, think again - this is how they celebrate!
:00:23. > :00:25.But first - an international group of doctors has warned the spread of
:00:26. > :00:29.the very serious disease, polio, has become a global health emergency.
:00:30. > :00:32.Polio worst affects young children, but it can be prevented with a
:00:33. > :00:43.simple vaccine and is almost never found in this country. It had been
:00:44. > :00:45.virtually stamped out worldwide, but countries like Pakistan and
:00:46. > :00:48.Afghanistan have seen rises in recent years. Now the World Health
:00:49. > :00:51.Organisation is calling for urgent action by the governments of these
:00:52. > :00:57.countries to use vaccines and stop the disease in its tracks.
:00:58. > :00:59.If this situation right now is not addressed, one of the deadliest
:01:00. > :01:03.diseases in history has the opportunity to resurge and we could
:01:04. > :01:06.lose the opportunity to eradicate this disease.
:01:07. > :01:09.To sport, and Liverpool saw their Premier League title hopes dashed
:01:10. > :01:12.last night as they allowed a 3-0 lead over Crystal Palace to slip
:01:13. > :01:15.away. Liverpool's players and fans were left distraught after Palace
:01:16. > :01:19.scored three times in the last 11 minutes to draw 3-3 - leaving Luis
:01:20. > :01:23.Suarez in tears at the final whistle. Liverpool boss Brendan
:01:24. > :01:29.Rodgers says his side's dreams of winning the league are over.
:01:30. > :01:35.You have got to have that maturity and management in the game to see it
:01:36. > :01:40.through, and we didn't do that. As I said, it was bitterly disappointing.
:01:41. > :01:45.Manchester City have two home games and I would expect them to go and
:01:46. > :01:48.win it now. If you've got any of these players
:01:49. > :01:52.among your football cards then you've probably got a strong set.
:01:53. > :01:56.With the World Cup starting next month lots of you are busy swapping
:01:57. > :01:59.these, but getting hold of the best ones can sometimes be frustrating!
:02:00. > :02:01.So Ricky's been to the City of London on the hunt for some tips
:02:02. > :02:08.from the experts. The City of London, home to some of
:02:09. > :02:12.the world's biggest banks. Every day, these men and women buy and
:02:13. > :02:16.sell all kinds of things to make money for themselves and the massive
:02:17. > :02:23.companies they work for. Getting the right deal can make or break a City
:02:24. > :02:27.trader. The trading floor might look like a very frantic and chaotic
:02:28. > :02:30.place but it is basically a group of people who are buying and selling
:02:31. > :02:37.different things, from currencies to oil, coal, gold and other metals. To
:02:38. > :02:41.be good at it, you have got to be one step ahead of the game. This
:02:42. > :02:45.kind of trading might be a world away from what you get up to in the
:02:46. > :02:51.playground, but there are some similarities. I have come here to
:02:52. > :02:55.find out what it takes to be a top trader in town but more importantly,
:02:56. > :02:58.in the playground. First of all, do your research, know your market,
:02:59. > :03:02.know what cards are out there, what are the good cards, what are the not
:03:03. > :03:07.so good cards, what are their strengths and weaknesses. We have
:03:08. > :03:12.Wayne Rooney here, what can I do to make sure I get the best card in
:03:13. > :03:16.return for this? You need to get these desperate buyers together and
:03:17. > :03:22.create a bit of an auction. Create a bit of excitement, get a bidding war
:03:23. > :03:26.going on in the playground, maybe. "So, I have got Wayne Rooney, what
:03:27. > :03:31.are you prepared to bid for Wayne Rooney," and get them competing
:03:32. > :03:35.against each other. And remember, think before you swap, don't do
:03:36. > :03:38.something you might later regret. Sometimes you need to sleep on a
:03:39. > :03:42.decision. Things might look very different in the morning. There you
:03:43. > :03:50.have it, some top tips on how to be the perfect card trader. I have some
:03:51. > :03:56.work to do. Buy! Sell! What do you mean, wrong number?
:03:57. > :03:59.Now if you thought the game of snooker was a quiet affair - it
:04:00. > :04:02.really isn't. That was the moment Mark Selby beat Ronnie O'Sullivan to
:04:03. > :04:09.become World Champion last night after a fantastic comeback. The
:04:10. > :04:17.crowds went wild. Afterwards, he dedicated his win to his father.
:04:18. > :04:21.When the going gets tough towards the end I thought I played really
:04:22. > :04:26.well. My father passed away when I was 16, before I turned
:04:27. > :04:29.professional. I always said to him I would try to win the World
:04:30. > :04:32.Championships one day and today it has come.
:04:33. > :04:35.And last up - it's considered one of the most impressive feats of
:04:36. > :04:39.engineering in the world - a tunnel that stretches 30 miles under the
:04:40. > :04:42.sea, linking Britain with the rest of Europe. The Channel Tunnel is 20
:04:43. > :04:47.years old today. This was the moment back in 1990 when the two tunnelling
:04:48. > :04:50.teams met in the middle - the tunnel was made by drilling out huge
:04:51. > :04:53.amounts of rock from either end. Now the trains carry 20 million people
:04:54. > :04:57.between England and France every year.
:04:58. > :05:01.That's all from me, Newsround's back this afternoon.
