I was impressed but I knew we can do it. Because Flick values physicality and effort also, we are not a technical side with fitness issues that can be bullied by physical teams anymore.
Only time we looked physically poor last season in Europe was at 4-0 in the tie vs Dortmund away.
If we can hold our own in terms of matching the physicality and speed of EPL sides, which I admit set the benchmark on these areas together with PSG and Bayern, then our superior technique can mark the difference, and vs Newcastle it did just that. We absorbed their heat well, and outclassed them with our technique in the end.
And we don't have to see the keeper making big game changing saves as some sort of a defensive problem. Almost all the teams that won CLs lately had keeper standout performances. Keeper is a key part of defense. Only Barca at City saw it as an aftertought, very glad we woke up. As did City.
Stegen and Ederson were the worst big club keepers and both of them have been cut, you can not afford mediocrity in goal anymore. Neither team is comfortably the best these days to carry an average goalie. If you want or have an ambition to win CL you need a keeper capable of making top saves when needed.
