A good team defends and attacks as a whole. At least since 1970 :)
Also, we went all in vs Spurs and got smashed. We need to be pragmatic and solid at Anfield. A big loss is the last thing we need now.
KDB has been injured and isn't in his best form. That's why he's been on the bench for the last month or so. Precisely because we have problems in defence, we can't afford to carry half fit players at Anfield. Give him a start or two against lesser teams before throwing him against top teams.
I hope he is fit enough to start and play like his old self, but chances are he is isn't. If we need him, sub him on with 20 minutes to go and hope for the best.
