This 2-0 win was really important for Chelsea as they couldn't win a game for 4 weeks in the league. They played dominantly against Tottenham and deserved it. They would have scored even more goals than this. And Ziyech was really marvelous. His goal was just spectacular and he was near scoring another one by a superb shot. He has been in-form these days and this helps the team a lot. Maybe Chelsea won't be able to chase Manchester City down for the championship but they can still end the season at the second place. But it seems really difficult as Liverpool are focused on catching up with Manchester City.
