I quite did not expect that Arsenal could be held to a draw by Atalanta, the game Atalanta showed was also quite good because it was able to keep up with Arsenal, after previously also Manchester City was held to a draw by Inter Milan, this squad from Serie A has a pretty good balance, however Arsenal is the most consistent team in the domestic league and always behind Man City but not strong against the Euro champions, honestly a pretty boring match.
Surprisingly in the first 4 minutes Leipzig got a goal quickly, but Atletico Madrid replied, this match was more interesting to watch than the Arsenal VS Atalanta match.
I must say I wasn't surprised with seeing a draw. But a goalless draw... It was a bit unexpected. Atalanta aren't a powerless team. You know they are the last winner of the Europa League trophy.

Just as I waited for, they stood strong against Arsenal. They might have even won if they didn't miss that penalty and the absolute goal chance a second after. David Raya did an incredible job there.
Arsenal want the PL trophy a lot at the same time. I'm very keen on watching how good they are going to deal with both competitions at the same time.
Atalanta seems to have the feasibility to compete in the champions league, the title of winning the Europa league is indeed worthy of them last season, the competition against Atalanta is a match that is indeed very undefended, yes the penalty that was wasted was an opportunity that was wasted but still saved by Arsenal.
The Champions League trophy by Arsenal seems quite difficult, for some reason in the Champions League Arsenal are not so good, as far as I know that Arsenal have always failed even to the top point of getting a chance to win, and they have never been a favorite winner, Manchester City, Real Madrid and Liverpool are always expected in the Champions league.
