Should Canaries say bye to Gunn or do numbers lie?

Canaries keeper Angus Gunn has been ranked bottom of the pile in the Championship for expected goals prevented so far this season.

According to an Opta statistic looking at all second-tier keepers to play 1,000 minutes or more this season, the Scotland international has conceded at least four more goals than he should have.

The metric subtracts the number of goals conceded by a keeper (in Gunn's case - 23) from his expected goals faced (where the relative shot quality of each on-target attempt is calculated and totalled; for Gunn it's 18.3).

That gives him an 'expected goals prevented' of -4.8 - a minus figure means the keeper has conceded more goals than he would have expected to.

Gunn's figure is the worst of any Championship stopper measured. Just above him is Derby keeper Jacob Widell Zetterstrom with -3.4 goals prevented, while at the opposite end of the table is Stoke City's Viktor Johansson on 13.5 prevented goals.

Do you think the Canaries need a new keeper if they are to get closer to the promotion race?

Has Gunn struggled as much as these numbers suggest - or is it a case of lies, damn lies and statistics?

Or are there other factors that contribute to Gunn's low score?
