With the tight schedule this season, it is reasonable that some teams will choose to rotate their squads when they have the opportunity, and I think that is the step that Arne Slot is currently taking. It's just that the results aren't great because, for the second time, they got less than optimal results and even got defeated this time. But that's not the end because there's still a second leg, and at that time Liverpool will play at home, it seems that this is the reason why Arne Slot dared to rotate the squad.
It can be said that the EFL is not so priority so some coaches rotate in this match so it is natural that there is a difference between the Premier League and EFL matches, they don't want when the PL starts there are some injured players this will be a big risk.
A 1-0 defeat is still hope for Liverpool playing at Anfield and I think Arne Slot can finish this in leg 2 well with his care.
