Considering the squad, England team is considered as favorite in this match. England's squad is comparatively stronger than Switzerland's. But if we compare the overall performance of these two teams in the past matches, then England team cannot be considered as favourites.
England have scored 4 goals and conceded 2 goals in their last four matches. The performance of England's attacking players is poor. England failed to win against Denmark and Slovenia in the group stage. On the other hand, the Switzerland team dominated the round of 16 match against Italy. won Share points with strong teams like Germany. So I would say Switzerland has a big chance to win in the quarter finals.
Looking at the squad, it is clear that England is like a favorite because there are many star players in it but not with its appearance, there are still many people doubting England when facing Switzerland because their performance during the group stage until now is not quite satisfactory.
Well that's the problem England's attackers are bad they seem unproductive even though they have many players who can score goals for example like Hary Kane but still it is still difficult for England, I agree that Switzerland still has a great opportunity than England.
