Comparing his performance in the league only between this season and last is probably the best way to look at it.
29 league games played last season and 9 goals returned.
29 league games played this season and 11 goals returned.
If you want to break that down into the actual minutes played, it’s 1 goal every 189 minutes last season to 1 goal every 165 minutes.
An improvement - but in the Premier League, those 11 goals put him equal 12th in the scorers list and his goals per minute rate not much higher even if you only included people who have scored as many goals.
Yes, he has scored more goals in other competitions, while I’m not discounting them - LASK, Toulouse, Sparta Prague & Norwich, who, as opponents, account for 7 of his 8 other goals - it’d be fair to call them lower level opposition.
I said ages ago 11-15 goals inbtge league only was a decent result, but for it to be a good season he needed to score 15+ in the league - I said a while back he’d end up on 14-16 league goals (I think) - I’m sticking by that.
15 League goals really should be the minimum for a player of Nunez supposed ability.
