I think the target routine of PSG is like that. They did well last season, but they cannot necessarily do it in the new season. Last season, we could see how some strong teams in the Champions League had problems with performance. Like Madrid and Man City, who I think did not perform optimally.
The new season will be a new challenge for PSG. Ligue 1 may not be a problem for them, but the Champions League is always difficult to predict.
Last season they had this uncommon drive that the champions league is one which they have not won befor and last season happens to be one of the seasons they have achieved a good height in the champions league with the kind of form they had and so they just looked for a way around it to making sure to win trophy. It will be a really difficult one to win repeat that again because in the final game of the club world cup they were looking fatigued and so they will need some more ti.e to rest except they improve then it is possible they could get a trophy but not likely the champions league.
It shows that any team can achieve success if they boost their squad depth, get a better coach, then sign players that are ready to play for the badge and work together with one mindset on the pitch. PSG was determined to succeed in the Champions League last season they worked hard to reach the finals and won it any team that's as determined as PSG and has a strong depth can do it too.
