Arsenal have been defeated 3-0 in a hugely demoralizing loss to Crystal Palace in the Premier League on Monday night.Goals from Jean-Phillipe Mateta, Jordan Ayew and a Wilfried Zaha penalty did the damage, with Mikel Arteta's men looking devoid of ideas.Having been so impressive in the second half of the season, the Gunners were expected to continue their pursuit of UEFA Champions League football.But they were defeated by former club-legend Patrick Vieira's Palace, who wreaked havoc on the Gunners' defense.Mikel Arteta will not be a happy man and neither will the Gunners faithful.Here are some reactions to the shocking Arsenal performance on Twitter:FK ☕️@fkhanageA half to forget. Every outfield player sloppy tonight. It is painful. Palace playing well and they’ve rattled us. Draw probably wishful thinking at this stage.8:46 PM · Apr 4, 20221023A half to forget.
