Defender delights in challenge
Highly-rated left-back Kieran Tierney says he's simply relished the challenge of playing in the Champions League.
The 20-year-old was again an outstanding performer against Bayern Munich in midweek having recently been rewarded with a new six-year contract at Celtic Park.
"It's making me a better player, more switched on, getting fitter as well," Tierney told BBC Scotland. "Coming up against the best players in the world so young, it is only going to benefit me.
"I know I'm still young and have a lot of learning to do and I'm under the right manager to do that, so I'm so happy," he added. "The club thought I was doing well enough and rewarded me with a good contract and I'm delighted. I'm very happy here and that's why I signed a long-term deal."
