Tim Vickery in South America

In the rollercoaster of tournament football it took Russia little more than a week to move from possible winners to definite failures at Euro 2012. Spare a thought, then, for Argentine club Tigre who could move to either extreme in the space of 90 minutes - or even be both at the same time. Next week is the last round of the conventional season in Argentina and Tigre have a good chance of winning the title for the first time in the club's long history. But they are also in danger of being relegated to the second division.
