Palmer, a boyhood Manchester United fan and the heartbeat of Maresca’s attack, pulled up clutching his groin. He had barely touched the ball before throwing his head back in frustration, shaking his head at the bench. Swapping his shirt for a heavy coat, the England international stormed straight to the tunnel in visible anger. However, he was later spotted back on the bench with ice packed onto his thighs. There were fitness worries about Palmer after he picked up the groin injury against Bayern Munich, and yet Maresca risked him for the blockbuster clash at Old Trafford. The gamble has backfired spectacularly.
