Kieran Tierney signs new four-year deal at Celtic

Celtic teenager Kieran Tierney has signed a new four-year deal with the Scottish champions.

The 18-year-old left-back made his Hoops debut as a substitute against Dundee in April, and has played twice more for his boyhood club.

Tierney, a Celtic youth academy graduate, is quoted by Sky Sports News as saying: "I'm delighted. I have been here 11 years already.

"To get a good contract for another few years at least is fantastic, and I'm happy to commit my future to the club I love."

The young defender also has one cap and one goal for Scotland Under-18s.
