Are all of the above back for the derby. Matip is very susceptible to pace, but is a much better defender than Gomes. Henderson was probably the biggest miss. Thiago and especially Mane would have made no difference. Liverpool dominated possession, but got cut to ribbons. Thiago in for Wijnaldum or Fabino would have made it worse.
I'm not sure if they are back. The issue in each case will be match fitness. Isolating for 2 weeks will have some effects, not with standing the potential there is a potential lingering effect. I'll be surprised, and quite pleased if this is the first start for Thiago.
For me I hope Henderson and Matip miss the game. Coleman has dominated Mane when theyve both played and I think Thiago is overrated and will underwhelm in the game. However if they can get Gomez out, and a midfield of Fabinho, Wijnaldum and Henderson they will have a strong base.
As for Klopp and Dortmund, yes it fell part. Bottom 3 half way through the league and clawed it back. They are potentially falling from a much higher spot. However to me this result is not really a freak result. They have started both conceding, and looking like conceding multiple goals for some time. It's been on the cards. I'm not sure Gomez and Arnold are sharp enough defensively, and the high line is a challenge.
You can actively see sides now wanting them to press. Have players who can switch play and you get at the back 4. It's a risk reward strategy, and some days it will go wrong, but theres a degree of volatility you would take when playing a top team.
