Dani Ceballos has urged Piers Morgan to be patient after an angry tweet blasting the club's decision to sell Pierre-Emerick Aubameyang.
Arsenal lost 3-0 against Crystal Palace on Monday night in a massive blow to the Gunners' top-four hopes.
In the wake of the defeat, Morgan said letting striker Aubameyang go was a huge error given Alexandre Lacazette's struggles up front.
Manager Mikel Arteta said after the loss: 'This is a moment now to challenge each other, to help each other and to believe again'.
In response, Morgan had tweeted: 'This is actually a moment when Arsenal fans need to accept Arteta made a massive season-wrecking mistake in giving away Aubameyang & relying on Lacazette to lead the line.
