UEFA Champions League is going on and we saw last match of Bayer 04 Leverkusen which they played against Bayern Munich full strength football team . Bayern Munich team performance is at top because that team players are in excellent form and they are giving hundred percent to win every match and now they won against Bayer 04 Leverkusen full strength football team. Bayer 04 Leverkusen team could not do any goal in this match and match was ended with result of 2-0. Kane was the person who did first goal of the match and he did this goal at 52 minutes of the match and after this we saw next goal from another player and that was Davies and he did goal at 71 minutes of the match.
You may have mentioned a match in the UEFA Champions League here, I think the two teams played with full strength in this match, that is Bayern Munich and Bayer Leverkusen played with full strength. But I believe Leverkusen didn't play well in the Champions League, so they played two matches against their fellow club Bayern Munich in the Champions League, but they couldn't score a single goal.
I had a thought that two teams from the German league would be able to play UCL in which one was true. Moreover Borussia Dortmund is in 10th place in the German league, yet they are the right team for the Champions League. Moreover, you also mentioned that Harry Kane scored the first goal, so also know that he managed to score a total of three goals against this team in the round of 16 matches.
