Celtic defender Erik Sviatchenko has revealed that his Denmark teammate raved to him about the ability and maturity of Scottish teenager Kieran Tierney during the friendly international on Tuesday evening, as quoted by the Scottish Sun.
Tierney has been a huge breakthrough star for the Bhoys this season after making his senior debut at the end of last campaign, and at the age of just 18 has established himself as the club's first-choice left-back ahead of competition including Emilio Izaguirre.
The youngster's consistent, mature performances have seen him earn rave reviews from players and pundits alike, and in February he was named at left-back in Spanish outlet Marca's best European Under-18s XI.
Tierney was rewarded with a first-ever call-up to the Scotland senior squad this month, and he made his debut with a start against Denmark on Tuesday night, making a fine goal-saving tackle before being substituted at half-time.
His Celtic teammate Sviatchenko, who came on as a substitute for Denmark after watching Tierney's first-half performance from the bench, said his national teammates were hugely impressed with what they saw from the hotly-tipped teenager.
Sviatchenko said, as quoted by the Scottish Sun: "I saw his first half from the bench and lots of my Denmark team-mates said, 'This guy is really good'.
"It's good for Celtic and it's good for Scotland as well that we have this young lad coming through and playing so well. He has taken to it like he is 30 years old. It's unbelievable."
In total, Tierney has made 25 appearances in all competitions for Celtic this season, and has been one of the first names on Ronny Deila's teamsheet since establishing himself as first choice in December.
It looks likely that his debut senior Scotland cap will be the first of many, despite having played for only the Under-18 and Under-19 teams for his country prior to that appearance.
