The former Wigan centre-back has been a key figure for the Gers this season.
All three were among a host of new faces drafted in over the summer and Kiernan feels quickly forming bonds has been key to the Gers excellent early season form.
“We’re kind of like a little family - that helps on the pitch,” said the former Wigan man, in quotes published by the Daily Record.
“It’s definitely helped with the togetherness because this is still quite a new team with people from different places. The quicker we can gel, the better. It’s good because you don’t want to be in on your own.”
The 24-year old, alongside Foderingham and Tavernier, has formed part of a Rangers defence which has conceded just six goals in the Championship this season.
Mark Warburton’s men have swept aside most challengers so far this campaign but were pushed the hardest they have been against Queen of the South on Saturday.
The Gers went behind to a Derek Lyle strike on the 35th minute before Jason Holt equalised early in the second half to set up a grandstand finish.
Rangers’ pressure took until the 90th minute to pay dividends with Martyn Waghorn’s header - and 15th goal of the season - snatching all three points for the Ibrox club.
It was a win will please Warburton in that he now knows - if there was ever any doubt - that his squad possess a grit and determination to match their quality in possession.
