Czech Republic stopper Petr Cech has become the latest goalkeeper to criticise the new Euro 2008 ball.
The 26-year-old feels the ball deviates so much in flight it is almost impossible for goalkeepers to judge where it will go.
The Chelsea keeper told Rotweiss, the online magazine of the Swiss Football Association: 'The new ball is really unpredictable.
'We will see lots of goals from 30 metres out. And the TV commentators will again say 'What was the goalkeeper doing there? He surely got his hand to it'.
'But the balls are so quick, they have scarcely any wind resistance and they can change direction any second, also in the last five metres. It therefore won't help at all to see the ball coming from a distance.'
Germany's Jens Lehmann had previously voiced concerns over the ball.
