Real Madrid's ruthless dismissal of Manchester City encapsulated 24 hours in which the Premier League's self-styled reputation as the best in the world suffered heavy damage.
City have a monumental job on their hands as they endured a similar – albeit less farcical – fate to Spurs, who lost 5-2 to Atletico Madrid in the Spanish capital 24 hours earlier.
Federico Valverde's brilliant first-half hat-trick puts Real firmly in control with a 3-0 advantage before the second leg of this last-16 tie, completing a sobering set of results for the Premier League's teams, who all have work to do to maintain their interest in Europe's elite competition.
