The odds are not high enough to make me bet on this game and since that's a friendly match everything is possible between these two teams there is even a chance for one team to don't take this game seriously, but still, I think the chance for Inter Milan to win this game in much higher than PSG because unlike PSG they were more stable and they didn't make too many changes in their teams while PSG even using a new coach in the next season.
Psg performance in this pre-season match was not very satisfying because they lost against Osaka. Although some people think that this pre-season match is a match that is not too serious, but in another context, Luis Enrique certainly failed to develop a good strategy in that game. It seems that some of the new players psg are still having difficulty adapting to Luis Enrique tactics.
For later odds I think Inter Milan can be the best choice to bet on them. I think the inter milan squad is very well organized for the games they have played. However, I would like to see a deadly duo presented by Inter Milan where Inzaghi can play Thuram earlier to see their duel with Martinez in the match against PSG.
