Why count whole seasons instead of normalising when there is a massive difference in total amount of years and games?
Why use 20 as a magic number?
Why only count goals and assists in premier league and not all competitions?
Why discount contributions from penalties and not from all set pieces?
Why count first six months of Bruno as a full season in terms of expected contributions?
Why discount first two years of Eriksen at the same time?
1: Because how you perform over the season is how a player should be measured, and not how we did with Pogba and called him an assist machine because he had 6 assists in his first 2 or 3 games some seasons back, and then went back to not assisting at all.
2: It's not a magic number. I could say 17 or 18 and Eriksen would still come better out of it because in every season he has played for Tottenham he has more goals and assists over a season than Bruno, apart from one season.
3: Because it is the league we play in and the league the majority care about. FC Copenhagen and FC Sheriff don't really interest me.
4: Because Eriksen was not on penalties, but Bruno takes our set pieces (Shaw has taken over now most of it now, though). It is also a lot more difficult to create/score from a set-piece than a penalty kick.
5: That's fair. His first season shouldn't be taken into consideration when we're talking about full seasons.
6: Well, I can if you want to. His first season he scored 7 goals and had 8 assists in 25 matches (1976 minutes played) which is a pretty good return, don't you think? In his second he scored 10 goals and assisted 2. Amount of goals are pretty good, but the amount of assists is very low.
Anyway, my point is that a number 10 can still create chances, score and assist without being so reckless and careless in possession (look at Ødegaard, for instance), and eventually that's what we're going to need. Having a hard worker as our number 10 helps, but often he needs to do that work because he lost the ball unnecessarily to begin with.
