You need about one very pacy player. Maybe 2, but it's not obligatory. Muller is anything but superfast and he's been incredible for Bayern. Lewandowski at 30 is not some superfast player either. Neither is Perisic at 30. You absolutely need a very fast player up front. But not several. You just need to use that player well enough and get him in the best tactical setup.
If Dembele will be fit, it can open up some interesting opportunities. Big if though.
Agree, I don't want more that one.
It absolutely does take many problems for the defensive line, simply because much lower pressure is put on the defense. Our defense collapsed because of constant pressure being put on these players. Bayern is actually the best example. Before Bayern started to settle and press well up front and in midfield both vs Barca and vs Lyon they could have received as many as 5-6 goals combined. But they've stormed that (also got lucky), and as the game progressed, their pressing scheme which involves about 6-8 players, started to work better, and the opponent was impeded from creating chances. Thus, their defense, in terms of pure defending skills 1 vs 1 was rarely tested after that bumpy start on their part. Almost every time Lyon broke the press from Bayern's first 6-8 players, their back 4 looked crap defensively.
The key is not to find elite defenders, because there are none. As I said, if elite defenders were around, Simeone wouldn't still use an average tall guy like Savic. The key is defending as a unit, with more effort, intensity and speed from everyone, to prevent the opponent to attack and press our back four at will.
You are missing the point here.
It is a team work, and yes attack and midfield play a part, but so does defense
That pacey defender change a lot. And It isn't just about elite defender. Prime Pique was elite defender but I won't take 2 Pique as starting CB . That is same reason I was against De Ligt (who most Juve fans think he was great in second half of the season) because he doesn't fit that need. As I said, I would take a Mascherano here despite having other limitations.
With no quick CB, you are in 1 of 2 situations:
1-You play with high line, press hard, but in such case you so vulnerable in counter attacks.
2-You make defense more deep, and this put problems for both midfield and attack. Defense will have more difficulty to help defense.
Again, it is all connected, your points are valid, but they aren't alone. And still need certain types of defenders to help it.
Gnabry goal against Bayern is good example, Thiago and Gnabry didn't hesitate to make the pass and run, despite defenders in big position. That is because they know -and instructed- to make those passes without worry since our defense is so slow.
You improve midfield and attack will help defense, but you still need to improve the defense too, and it will also improve midfield and attack themselves in return.
