No, Tottenham didn't play badly but Ramsdale aka Arsenal's goalkeeper is playing very good since there's many shoots from Tottenham was on target, but Ramsdale successfully block all the shoots. There's still 18 weeks to go, but it's hard to see Arsenal will lose for 3 matches considering they only suffer 1 losses in 20 matches.
Arsenal played pressing in the early minutes of the match, so Tottenham's defense was very busy maintaining the attacks they were building. Tottenham did not play better than Arsenal in this match so they lost. Tottenham managed to create seven shots on target, but because Harun Ramsdale played quite well, he was able to ward off these shots which made Tottenham have no chance to score. Hugo Lloris played quite badly and made several blunders in that match.
The many mistakes he made and the process of the first goal came from a mistake by Hugo Lloris who caught the ball imperfectly, so that the ball headed into his own net, in the 36th minute Martin Odegaard managed to score one additional goal, thus completing Arsenal's victory in the North London derby.
I see Arsenal is similar like Napoli where they're not sign a player with fantastic performance and popular, but they're just sign new potential player and improve the player to have fantastic performance!
Arteta was able to make changes to the Arsenal squad, even though there weren't many great players there, the combination of players that Arteta always installed was able to carry out his duties quite well, so far Arsenal have been very consistent in playing in the Premier League.
Considering Arsenal isn't the most popular and rich club in Premier League, do you think they will let Odegaard and Saka to join the other club? I believe many clubs are paying attention to this both players.
Arsenal's vision of always selling players for profit has changed, because if you look at the start of the season Arsenal were even willing to buy players at a higher price, this had not been done for decades since being coached by Arsene Wenger.
Both are important players in Arsenal's current squad and I'm sure Arteta won't let them go.
