You mean not underestimating opponents?
Realistic not your thing then?
How often do Arsenal beat United? Not very.
Palace have beaten Chelsea, Liverpool, and put 3 past Arsenal recently. What makes you think they'll be a pushover?
Interested.
Palace have just become pretty much the only team to lose at home to Burnley all season. Their good form was based around Mamadou Sakho single-handedly being responsible for a solid defence, and he's injured.
Mourinho has already said he's playing a B team for Arsenal because of the Europa league.
