Chelsea ‘punished for mistakes’ in shock Carabao Cup defeat to Middlesbrough, Pochettino says

Chelsea boss Mauricio Pochettino said his side were “punished for their mistakes” in a 1-0 loss to Middlesbrough in the Carabao Cup semi-finals. Hayden Hackney scored the only goal of the game as the Championship side stunned their Premier League opposition. Chelsea have a chance to turn the tie around at Stamford Bridge in the second leg later this month but will need to be far more clinical to reach the final.
