When subs go wrong Erik ten Hag has earned a lot of praise for his substitutions this season, but the triple change he made after 62 minutes of this game will not fall into that category.

Neither are much of a threat in front of goal. It was a risk replacing that trio of players in one go, but it was an even bigger gamble when the drop off in quality is so stark, with the notable exception of Christian Eriksen.
