We don’t have a huge number going to this WC, plus looking at the draw, I would expect only 4 of our players going beyound the QF (Allison and Fabinho with Brazil, VVD with Holland and Konate with France), so I would expect a fairly strong team for the 4th round match with the only reason to rest anyone being if someone’s team makes the final which would likely drop that down to 2 - Allison and Fabinho, unless Brazil manage to implode before the final, so barring anyone getting injured in WC Klopp should have a relatively fully fit squad to pick from.
I say play everyone to knock some of the rust out before restarting the league
