Gabriel Jesus was not unlucky in the match that he did not get a goal. If you watched the match you see that Jesus was dropping deep into the midfield even when Saka was not injured. I didn't actually know why he was dropping deep but I know it's by the instructions of the coach. After Saka left because of injury it continued that way.
Gabriel Jesus worked hard for the match; if you watch the game, you will see the type of work he did in the game; he played from the midfield and provided two assists; goal scoring is one of his priorities, but he is always happy when the team wins even if he does not score. However, near the end of the game, almost all of the team players wanted Gabriel Jesus to score a goal, but he was unlucky and defenders prevented him from doing so.
It was rather fortunate that Gabriel Jesus couldn't find the back of the net when he had his opportunity, but it was work rate that ensured the gunners had goals to score. If a team like this determines to win, no one definitely can stop them. I look forward to their other games and Europa, sometime this week and hope to see the Arteta men fire the cannon of goals to outshine the opponent.
Arsenal has renued a confidence in the fans that has long been absent. Way to go gunners!
Playing at home against a weak team and Arsenal can win big with a score of 5-0 indeed, it is bad luck for a striker who can't score a goal. Even though Gabriel Jesus was able to make two assists, but that was not enough because of course as a striker Gabriel Jesus should have been able to contribute in making goals for Arsenal's big win.
Regarding Arsenal's last match in the group stage in the Europa League, I believe Arsenal will still aim to win, even though Arsenal have already qualified but Arsenal can still be runners up if they only draw and lose, because PSV as the team below can still take over the group winners. But even so, I believe Arsenal will not put too much pressure on their squad to win big, because Arteta will also certainly rotate considering that after that Arsenal will play away against Chelsea in the English Premier League.
