Manchester City lost 2-1 to Brighton & Hove Albion in the Premier League on Saturday, thanks to late goals from substitutes Joao Pedro and Matt O'Riley that gave the champions their fourth consecutive loss in all competitions.

The defeat marks the first time City coach Pep Guardiola has lost four in a row in his managerial career and kept his side second in the league standings on 23 points from 11 matches. Brighton climbed to fourth on 19 points.

City looked poised to end their run after Erling Haaland scored in the 23rd minute when Mateo Kovacic threaded a long pass between Brighton's two centre backs, and the Norway international booted in his own rebound.

Brighton improved after the break and Pedro drew the hosts level in the 78th minute when City could not clear the ball and the Brazil international pounced to lash it past Ederson.

"Last season we dropped too many points and the gaffer told us to believe in ourselves this season and we are doing well this season against the big teams," Pedro told Sky Sports.

O'Riley made his Premier League debut a memorable one when he secured the well-earned victory five minutes later, latching onto Pedro's through ball and slotting home from close range past Éderson's outstretched arm.

Guardiola will rue City's squandered first-half chances, including a couple from Haaland in the span of a few minutes that on a different night could have seen the Norwegian celebrating a hat-trick.

The first chance saw goalkeeper Bart Verbruggen dive to stop a blistering Haaland shot with his right ankle at the near post. Haaland then headed just over the bar.

While Brighton had only 39.5% possession, it felt like a goal was coming in the second half. The hosts had a terrific chance soon after the break when Jack Hinshelwood leapt high to head down a looping cross from Pervis Estupiñán that an alert Ederson swatted away.

City have been hit by injuries with Nathan Aké, John Stones, Jack Grealish and Rúben Dias missing on Saturday, alongside longer-term absentees Rodri and Oscar Bobb.

Their previous three defeats were a 2-1 loss to Tottenham Hotspur that eliminated them from the League Cup, a shock 2-1 league loss at Bournemouth, and a 4-1 Champions League thrashing by Sporting that had midfielder Bernardo Silva saying City were in a "dark place".
