The defender and born-and-raised Celtic fan is aware he will have to work to keep his cool in the Old Firm Scottish Cup semi-final next weekend.
Celtic defender Kieran Tierney has told the Scottish Sun that he knows he will have to work to ensure that he does not lose his cool and do "something silly" against Rangers in the Scottish Cup semi-final next weekend.
The arch-rivals meet at Hampden Park on Sunday in a hugely-anticipated clash off the back of the Gers having secured the Scottish Championship title and Challenge Cup glory.
Tierney, a born-and-raised Celtic fan who admitted he can still remember watching Old Firm ties of years gone by from the stands as a supporter, is expected to keep his place at left-back in Ronny Deila's side for the game.
The 18-year-old Scotland international, who has enjoyed a remarkable breakthrough for the Hoops this season, admits that the atmosphere on Sunday will be like no other he has experienced so far in his playing career.
Though he vowed not to duck out of any challenges in what is likely to be an intense, emotionally-charged match, he acknowledged that he will have to be careful to control himself whilst his blood is pumping.
Tierney told the Scottish Sun: "I will do my best to adapt to the game because it’s kind of a different atmosphere to any other game.
"Everybody knows that and it’s just down to us as players. I probably would be more nervous as a fan. These are the games fans enjoy because the atmosphere is electric.
"I won’t shirk any tackles but it’s also important for me not to get too carried away — and end up doing something silly."
Tierney's Celtic are moving ever closer towards sealing a fifth consecutive Scottish Premiership title after their 2-1 victory at Motherwell and Aberdeen's 2-1 defeat at Hearts left the Bhoys eight points clear at the top.
They are being billed as big favourites for the cup clash, but with Rangers having lost just four of their 44 competitive matches in all competitions this season, Deila's side would be fools to take Mark Warburton's men lightly.
