Apparently Liverkusen wanted to start their new winning streak, but it didn't work out. In general, nothing terrible happened, both teams learnt some lesson from it. EPL matches will start tomorrow, and the day after tomorrow Arsenal will play their first match and I think it is very important to start the season with a win, not so much for the position in the standings, but for the morale-booster
Leverkusen almost broke history but on a norm, Arsenal is their mate. They had last season quite boldly in Bundesliga but they couldn't hold Atalanta down and lost the winning streak in the Europa League final and it was then I knew they are not as good as they are, if they should have won the final match and take out Atalanta that wasn't even having a good Place in their domestic league but this is a new season, let's see what they can play this time.
Arsenal has shown no sign of weakness, Arteta seems not to have cool down but the task ahead of this season might look hotter than last time because Guardiola lost FA cup and Champions League, the dominance to maintain the lead might come back to his head and who knows if there is going to be surprises later when the season begins.
