Because they look even worse than the other options at this moment in time.
But surely we'd hope they've room for vast improvement. I can't believe sandro isn't at least as good an option as DCL and niasse if he finds a little form. Just not sure how he can find it when he can't even make a bench now
Same with klassen has he really been that much worse than Sigurdsson. Surely we could give him 20 minutes for Sigurdsson and see if he can play himself into some form.
We are poor. I'd sooner risk these players in worse form who might have higher ceilings
