Juve won the first-leg 3-0 at Parkhead.
âIf you didn't watch the game then you might think we cruised to victory,â the Italian international commented.
âWe have to be honest though as the game hinged on a couple of decisive moments. But it's a positive sign that things went our way and also that we took our chances.â
âCeltic are an excellent side and they showed that,â the former Parma man noted.
âWe set out to attack them, but struggled to get into our rhythm so we had to settle for what we could manage, which was to defend well and break forward on the counter.
âWe did a great job of it too â we were clinical and ruthless.
âAre we already through? It's not good for us to be too relaxed. We must remain focused and keep showing Celtic the respect they deserve.â
