Liverpool boss Arne Slot was downcast about the possible extent of the injury to Bradley, which occurred in the fourth minute of stoppage time at the end of the match as the full-back attempted to clear the ball.Bradley, who later left the Emirates on crutches with his left knee in a support, went down after falling awkwardly near the touchline and was in some discomfort before Gabriel Martinelli dropped the ball on him then attempted to manhandle him off the pitch.It provoked a furious reaction from Liverpool’s players, at the end of a match that had been low on talking points with neither side creating many chances.
