Goalkeeper Petr Cech today claimed to have the secret weapon that will help Chelsea to a Premier League and Champions League double - his new orange kit.

Cech believes the striking design is scientifically proven to distract players when shooting for goal and will wear the top in the Blues' crucial title showdown against Bolton on Sunday.

The 26-year-old is also almost certain to use the new kit against Manchester United in Moscow and claims the new adidas shirt, labelled 'Warning' by club officials, will boost his side's chances of success.

"Studies say the orange colour spreads the most when the striker attacks, in the split of a second as he focuses," said Cech, whose side need to get a better result at Stamford Bridge than United achieve at Wigan to win their third title in four seasons.

"This colour is like a sort of alarm or alert which really spreads and is very difficult to avoid, so this should be good for me."

Aside from the eye-catching colour, Cech's new jersey could clash with United's red shirts in Moscow on 21 May.

A UEFA spokesman said: "Chelsea's goalkeeper jersey for the Champions League final match will be fluorescent orange. The reserve jersey will be dark grey. The referee of the game always has the final word regarding the jersey. Therefore it is impossible to say today which jersey Chelsea's goalkeeper will be wearing in Moscow."

Kit issues have been raised in the past, with United famously changing from their ill-advised grey strip at half-time in a match they were losing 3-1 at Southampton in 1996, after Sir Alex Ferguson claimed his players were struggling to identify each other against the backdrop of the crowd.

Mexican goalkeeper Jorge Campos designed his own eccentric jerseys in the 1990s with the aim of increasing his popularity and distracting the opposition.
