Failing to advance to the final round left a deep wound for them, Arsenal had sacrificed the EPL to focus on the UCL, in fact they were unable to complete this competition with achievements.
Luis Enrique PSG have emerged as a fearsome team for EPL teams. They beat Man City in the League stage, then knocked out Liverpool in the last 16, Aston Villa in the quarter-finals and now beat Arsenal in the semi-finals.
Luis Enrique experience and ability to strategize has opened up new hope for PSG, now they are one step closer to glory in European competition.

Arsenal began this match very well with their good approach to attack PSG proactively and seriously after a match beginning. They actually created enough not only pressure but also opportunities in first 8 minutes and came very near to a goal that would be an aggregated equalizing goal for them. Unfortunately they lacked of accuracy in shots to equalize the result and to make remaining minutes of the match more easily for them.
Even after PSG scored and led with two goals, Arsenal scored one goal and some minutes after that goal, they again created enough pressure and opportunities for an equalizer. If Saka had equalized temporary result of this match, with 2 - 2 goal, Arsenal would have made bigger pressure and had chance to score a third goal. They wasted many opportunities in this match and will have to regret about that.
With this ending in Champions League, Arsenal will focus more on their remaining matches in Premier League for securing their second position. This change will result in harder competition among other clubs for third, fourth and fifth positions as Arsenal position in top five will be likely secured.
