Ajax and Liverpool also secured their way out of the group in the 1/8 finals of the Champions League with their victories. Hummels' removal caused a lot of questions, considering that Antony himself stepped on Hummels' foot. Therefore, this fact may slightly explain the comeback that Ajax made. Atletico Madrid failed to score a single point in the matches with Liverpool, which looks quite surprising and has already complicated Atletico's struggle to get into the next stage of the Champions League and allowed Porto to reach second place in the group. Also, Milan still had chances to continue the fight, but still the draw with Porto greatly reduced these chances.
So, it just means Ajax has beaten Dortmund twice within some weeks.
Football!
I am yet to know what works the best for any club;
Is it to have a solid defence like Chelsea, such that any match you managed to score 1 or 2goals you have won.
Or to have good attack, like Liverpool that will get much goals, even if you equalise, it will result to GG and win for them.
I am asking because Ajax ability to score much goals have been helping them even in their league.
I don't think it is optional in this case mate , you just mentioned everything that makes an out standing club side.
The club can't really depend on one to win matches; these is what you should understand,when once a team begins to conceive much goals, 1 2 3..5 because they haven't gotten a formidable defense,it weakens and discourages the players and they might end up not playing well to equalise even if its a good team of good attackers,also on the other hand too
The best thing is to build your team as a club,not individually
