Mark Warburton's Glasgow Rangers side are preparing for their return to the top flight after several years away.
Rangers' Kenny Miller
Mark Warburton's squad are preparing for their return to the Scottish Premiership after spending four seasons trying to make it back to the top flight.
And although Warburton has bolstered his side with eight new signings during the summer, while some supporters may look at the stars from last season as key men for the club - the likes of James Tavernier, Barrie McKay and Martyn Waghorn, for example - former Gers defender Bocanegra believes that it is the 36-year-old that has a crucial role to play next term.
"There are only a few guys I know from my time - Davie Weir, of course, and Barrie McKay who was breaking in," he told the Evening Times.
"But I also know Kenny Miller, of course, who is a very important guy because he has so much experience."
While the new signings like Joey Barton, Clint Hill and Niko Kranjcar bring bags of experience with them to Ibrox, they are yet to play at the highest level in Scotland and, with the exemption of the Croatian, are arguably yet to play for a club where the expectations are as high on a domestic level as they are at Rangers.
Miller, on the other hand, has four Premiership title medals under his belt so will have an idea of what the squad will need to do to challenge the likes of Celtic and Aberdeen next season, and should be able to help the less-experienced members of the squad if they get themselves into a position during the latter stages of the campaign where they find themselves genuinely battling for the title.
