It wasn't an easy win for Arsenal despite being in control especially in the second half. But getting three points was the important point of course. Trossard hasn't been scoring a goal in Premier League games for a very long time. But today he scored the winning goal and finally finished this bad streak for himself.
Things are going well for Arsenal in the league. But they might need to improve their performance a little more in the long term. This is important for especially big games. Their next game is against Tottenham in Emirates so I really wonder how this game will end.
The performance of Tottenham is far from what we saw from then in the past, especially in the last season.
We know Tottenham didn't have a good performance and that's why they fired their coach in the last season, also Tottenham didn't have a good atmosphere in the team and when Kane left then I thought they would show poor performance.
But a miracle happened and in the game, they had against Sheffield United, Tottenham scored two goals in the waisted time to win the game.

Tottenham are really interesting this season indeed. But the most important thing has always been to improve their team performance. As they were weak in this before even Kane's high effort wasn't enough to save the team. But now it seems like the new manager is doing a good work about this situation.
The game against Sheffield was really interesting. Richarlison became hero after entering the game by a goal and an assist. This was important for him to take back his place in the starting eleven faster.
