Arsenal taking the first lead of the match and ending up playing a 2-2 draw wasn't impressive, considering their performance in their last few premier league games, especially the Saturday game. I thought they would win sporting but sporting gave them a tough time, Arsenal was lucky, if they lost the game their return leg won't be assured that they'll survive it. Hence, I'd assume they were exhausted from few days match gaps that's given to them, they just finished playing premier league on Saturday and yesterday Europa. Regardless of scores I enjoy watching Arsenal games they spice up football and it's the reason I love watching Arsenal games. Let's look out to the outcome of the second leg.
For Arsenal, this is a good result, two goals scored away, and a draw is an acceptable result, after all, Sporting were participants in the group stage of the Champions League. There will be support from the fans in London, this will add strength to Arsenal, besides, they play better at home, so I think that they will have more chances to win.
And as we can see, everything is in order with Manchester United, the defeat from Liverpool did not become something insurmountable for them, it's good that ten Hag managed to find the right words. The victory is quite confident and it almost guarantees them access to the quarter-final.
