I wasnt happy how we started 2015 final. We looked a bit scared, especially after conceding early on. In the 2nd half we played on par with Barcelona. But you have take into account that Barca's players had more experience playing finals and reaching later stages of the CL, while this was our first final after 2003. Also, our Italian players were often on the losing end when they met Spain, which were Barca's core, so even before the kick off, psychologically we were behind. Not to forget no one actually expected Juve to reach the final in the 1st place, especially after drawing Real in the semis.
2017 final, meltdown during the half time, before that we were ok. 2nd half you could notice players' minds were elsewhere.
3rd time's a charm?
