I don't agree with this statement, even though the Premier League competition is known as one of the best leagues in the world, this competition is attended by 20 teams with different levels of strength. Talking about Underdog teams, almost all competitions have teams with these criteria. Newly promoted teams or teams that always struggle at the bottom of the standings are very easily defeated by teams that dominate the EPL.
Arsenal victory over Crystal Palace did not really surprise anyone because these two teams have very big differences. The additional three points won in front of his supporters have revived Arsenal's hopes in the EPL title race. Arteta needs to keep the team's performance consistent in order to reach first place at the end of the season.
The Premier League has always been one of the most popular leagues, even those who are not very keen on football know about this tournament.
After Arsenal's victory, it is easy to say that we did not hesitate in their victory, but before the match everything was not so obvious, before this match Arsenal had several lost matches and Palace is not the easiest team to defeat so easily.
But Arsenal managed to achieve such an important victory for them, they won the first half 2-0 and it was clear that they were not going to lose this match. 5-0 is a very confident victory, I expected Arsenal to win, but I thought the match would be difficult.
