Actually, Champions League is the highest level soccer there is. Even better quality than WC (because club teams can work together much longer). HOWEVER, this is a play-in game. Only 1 of these teams will make the top 32. The highest rated teams go directly into the Group stage (Real Madrid, Barcelona, Chelsea, Bayern, etc). AND both teams are way off form this early in the season. Arsenal was missing probably 4 starters. Check it out when the Group stages start in Sept/Oct. Teams will be up to speed by then.
