Shergar reverse-jinxed Germs. He did a fine job of reverse-jinxing Chelsea at every opportunity this year too. He is the Matth of 2014
The worst jinx is Mick Jagger. It might be superstition but apparently every single team that Jagger said he supported before a big match (in different sports) lost. Most had been favourites beforehand. Before the semifinal he said he supported Brazil and that Brazil was bound to win. And he went to the match. Now he is getting thousands of hate mail and abusive tweets on the web. Matth is not in the same league. Although it seems that 90% of his predictions last season did not come true (sorry Matth it probably just seems that way!). But Matth (semi-joking) if you predict and start a thread "United will not even get 4th place next season. Discuss" many of us will be very happy...
To quote one of Matth's famous Twitter posts. Big game bottler they said. World Cup winner they never said
