No room for underestimating zones here. Italian teams have been underrated over the years and we can remember vividly how Inter Milan knocked out almighty formed Barcelona out of the UEFA Champions League and we had to see the competitive strength of this particular club. Surprises will always come either from Seria A teams, La Liga teams or the EPL. These clubs put in much more efforts to accumulate a win and they will always come for the big win.
All teams have an equal chance to compete for the title, but looking at the quality of the players in each team reveals the quality of the team's competitiveness. Inter Milan has been quite good at eliminating some strong teams, but they have always failed to reach the championship final. This season, I see the Premier League representatives as having a better chance, although I'm not discounting Bayern Munich, Real Madrid, Barcelona, or PSG. Anything can happen, as football sometimes goes unpredictably.
