And although Kellock was widely praised for his performance, the Warriors lock was quick to praise his team-mates for their attitude shown at the Estadio Jose Maria Minella.
The 29-year-old said: "I heard that the likes of John Beattie and Andy Nicol commentating on the two games were giving me credit for my 'leadership' but to be honest, it's what I've been doing ever since I joined Glasgow four years ago.

"The back-row of the two Johns (Beattie jnr and Barclay) and Kelly (Brown) have gained great credit for their displays for Glasgow and they showed they are very effective when playing for Scotland.
"The Edinburgh boys made a terrific contribution but a special mention must be made of my Glasgow team-mate Moray Low who showed in Argentina that he has come of age and can mix it with the best of them."
