Naby Keïta was taken to hospital after being carried off the field on a stretcher suffering from severe pain in his back during the first half of Liverpool's 1-0 Champions League defeat. "Then the timing for our defensive movements were not good enough, we didn't close the spaces in the right moment, we didn't react in the right situation and so they could play through our formation".
