PSG have a lot of strikers, but that doesn't mean they will be easy to beat Madrid. Currently Madrid are on-fire in the domestic league and are doing quite well in the play-offs with 5 wins. However, what made this match interesting was that it was like Messi met his opponent during La Liga. And Ramos is back not as captain of madrid, but as their opponent. But, in other hand, experience of Ramos and Messi in La Liga, may be difficult for Madrid to win.
Interesting as for this match, it's a long time coming. Ramos will meet with his former club. At least Ramos already understands how madrid and that's PSG's advantage. But in the end I agree with you it will be difficult to guess the final result. Maybe they should make the most of the game at home, because it will last 2 legs. Of course the first game should Madrid can win without conceding. At least Madrid should also win 2-0. With a margin of 2 goals of course Madrid will feel more confident for the 2nd leg in Paris.
