Manchester City manager Pep Guardiola has praised Erling Haaland as the epitome of an all-round goal-scorer and believes the 20-year-old striker is setting standards few have ever reached at his age. Haaland will be the biggest threat to City when Borussia Dortmund arrives at Etihad Stadium for the first leg of their Champions League quarterfinal on Tuesday, having scored a competition-high 10 goals this season. He is also the youngest player to reach 20 goals in the Champions League — at 20 years, 231 days — and he got to that milestone in just 14 games, also a record.
