I remember some seasons ago when I said repeatedly that for PSG to win the champions league, they will need to have a team with more bond and rarely a superstar. He could be a good player and not that exceptional kind of player.
1. Neymar could not do it
2. Neymar and Mbappé couldn't also do it.
3. Neymar, Mbappé and Messi also didn't do it.
It shows that individual names don't win the champions league but w good team does. Who could believe that PSG could go this far without the above trio.
Soccer is 11 players game and here for having win at highest level coaches also needed good strategy and mentality currently Luis Enrique is doing good job and playing without big names are also giving him good advantage. He is having good experience while doing this job at Barcelona they already give exit way to three English clubs now facing uphill task against fourth which is also looking good for them, but Arsenal is also currently capable of giving surprise in second leg this could be going interesting competition.
Both PSG and Arsenal are balanced with good quality players, so this can still change but PSG is having the best chance of winning here even Arsenal is also looking impressive, but they still lack of creativity which is also important for winning top leagues.
