Celtic players Tony Watt and Fraser Forster have spoken of their joy after their team beat Barcelona in the Champions League.
It'll take a couple of hours to sink in. I just saw (Victor) Valdes, I thought to put it to the side of him and it might go in. It's probably the best moment of my life, I'll look back at it when I'm older and think 'We've just beaten Barcelona in the Champions League' - there's nothing better.
It's tremendous, I don't think words can describe it. We put in so much effort at the Nou Camp and couldn't see it through, and tonight we've seen it through. We had a good look two weeks ago and we knew what we wanted to do. Everyone was tremendous, everyone played their part tonight. We defended really well and Tony came on and scored a great goal; his goals-to-games ratio is incredible.
