FORMER Republic of Ireland colleagues Jeff Kenna and Damien Duff are set to test each other's mettle at St Andrews.

For rising star Duff, the only player to bring some sparkle to Rovers lack-lustre season's opener against Sunderland at Ewood Park, it will be another chance to stamp his international class credentials on the fledgling season.

And, with him set to sign a new deal for Rovers, he will want to underline his commitment to Graeme Souness's cause with another strong display.

For ex-Rovers defender Kenna the challenge of stopping Duff will be one he will be hungry to take on.

After leaving Ewood there was a short spell at Wigan before signing up to the Blues as their bandwagon rolled into the Premiership via the play-offs.

Opening day defeat to Arsenal at Highbury was hardly a yardstick to how the Blues will fare and Kenna and his team-mates will be well aware that impressaing aginst the likes of Rovers holds more of a key to their survival in the top flight than how they fare aginst the division's glitterati.
