In all fairness, I can understand why the club did it, had we been in Liverpool's league position I am sure we would have sent a totally different X1. Right now, we have our biggest chance of challenging for the title in many many years.
I am sure Daniel Levy's first target for the club will have been to be in CL next season. We all know winning the EL does that, but it still takes some doing, although playing our best team v Dortmund improves that chance, I am not sure we would still have won.
Whereas via the league we are probably 12pts from 8 matches away for a Top 4 finish (possibly even less), having our best team available for the remaining 8 games gives us a better chance for me.
If it all backfires and we end up 5th, well that's another story
