Having survived a chaotic situation when the Dutchman nearly netted once more in his own net, their situation enhanced moments after when the Netherlands forward was tripped outside the penalty area by the English center-back.
There was a moment's hesitation among the defenders when Fernandes rolled the set-piece toward Mount and that allowed him to beat Henderson using a fierce strike.
