PSG is well prepared as we can see from how they have started to where they are now, they've got all it requires for them to win the finals except anything beyond expectations happened, though as we already know that football is a game of luck, anything can happen with match, we may not know the outcome until it is finished.
Regarding Inter Milan, we can also see how far they gone in waging the war till they acheive to this extent, which I also believe that with all desperation, they are not willing to take it likely on PSG this final, but at least a winner must emerged from them all, while am very sure PSg is going to have more higher odds over Inter for those playing the bets, but I will only support PSG to win because they needed it most.
PSG was underrated and even people even make trends about them in featuring in the farmer's league, Ligue One because they've been constantly and consecutively winning the domestic league titles without any tough rivals. Paris Saint-Germain have been built for the core position and with standing equation, I can beat my chest that Luis Enrique is the main reason why Paris Saint-Germain are in the UEFA Champions League final this season. The manager didn't waste any atom of time when he spot an opportunity, he saw it and grab it with full hand and chest, he's having quite good time in Parc des Princes stadium.
Where is Barcelona and Arsenal? These clubs have been proven to be the favorite to win the UCL but everything change right? They both got eliminated in the UCL semi final though they did a great job and settle for lesser position. Paris Saint-Germain succeeded in thrashing every elite EPL side they face, Manchester City, Liverpool, Aston Villa and finally Arsenal to get to the UEFA Champions League final.
