Mateta admitted the collapse of the deal was difficult to process at the time. The striker focused on regaining his place in the Palace side after returning from the setback.
"Honestly, it hurt me psychologically at the time, when they told me it had fallen through,” he told L’Equipe. “Then, I quickly reflected on how to recover. I consulted several specialists and they assured me there was no need for an operation. I focused on the next step, until my return. I worked hard to show Oliver Glasner that the ‘JP’ leader was there to take back his place and win with the team."
