With usual number one Martin Dubravka injured for the first part of the campaign, deputy stopper Karl Darlow stepped in to fill his boots to great effect, only to be dropped from the starting XI against Wolves and West Brom.
Given the form that Darlow had shown for the vast majority of his stint with the first team, there will have been those in the club's fanbase who questioned the decision to bring Dubravka back into the side, and it’s hard to argue with his statistics.
So far this season, the 30-year-old has conceded 44 goals in all competitions despite having an xCG (expected goals conceded) of 48.85.
That means that he has prevented nearly five almost certain goals.
As a point of reference, Dubravka has prevented 0.76 xG during his two games in the Premier League this term.
