Warburton said: “He has that desire to become better and I think that Rob Kiernan is capable of going and playing in the English Premier League. Rob has everything in his locker; he is both technically outstanding and physically at six foot three. The work that he does at Murray park day in and day out is fantastic – he has everything and I think that he could go on to play at the highest level.”
Kiernan arrived at Rangers over the summer, linking up with Warburton who had coached him as a youth player at Watford.
His career had seen him as something of a journeyman in the lower leagues of English football, and he never managed break into the senior Irish squad, despite being highly rated at youth level and capped 14 times.
His longest spell with a club was with Wigan, playing 32 times, but since moving to Rangers over the summer he has already played 26 times.
He has excelled at centre-back and been arguably the best defender for the Gers this season, earning rave reviews for his performances as a ball-playing centre-half.
Still just 25-year-old, Kiernan has plenty of years left to develop, and working under Warburton will be fantastic for his growth into a truly top class player.
Warburton believes Kiernan has the potential to go on and play in the Premier League, but as good as he has been this season, he will have to prove himself in the Scottish Premiership before having any dreams of turning out in England’s top flight.
