My guess would be he's afraid we miss de Jong's protection so he went for Nico to clean after Busquets. I thought we'd see Roberto there.
Also, benching Araujo makes no sense if it's not due to discomfort.
Araujo is on the bench, shouldn't be injured. But might be some discomfort he felt this morning.
Guess it'll be a 4-2-3-1 with Nico-Busquets double pivot, Depay - Gavi - Coutinho, and Luuk upfront.
