Let us look at the FACTS. I will take the following:
(a) minutes per goal
(b) minutes per assist
(c) minutes per assist or goal
First, consider last season, certainly RVP's best-ever season.
2011-12
Edin (a) 108 (b) 302 (c) 79
RVP (a) 111 (b) 237 (d) 75
Quite close, actually. Indeed, if penalties were excluded, the minutes per assist or goal would be 79 for both! The latter is really quite astonishing given:
(i) Arsenal's strategy focused around RVP, whereas City's strategy (by common consent) did not play to Edin's strengths; and
(ii) whereas RVP was on the field for the full 90 minutes in 34 of his 38 premier league appearances, Edin was 'chopped and changed', i.e. he was on the field for the full 90 minutes in only 10 of his 30 premier league appearances and, for 10 of his appearances, he was on the field for a TOTAL of 82 minutes.
Let's consider their CAREER statistics.
Edin (a) 151 (b) 363 (c) 106
RVP (a) 241 (b) 490 (c) 161
Clearly Edin DOMINATES RVP. (If penalties were excluded, the minutes per goal or assist would favour Edin even more).
I don't know what the claim that RVP has been "a shit hot player for years now" really means. Incidentally these career statistics question the frequent claim that RVP's poor goal scoring record up to and including 2009-10 were due to injuries (to state the obvious, the above relate to time on the pitch). It is also claimed that RVP's poor scoring record was due to his starting out as a winger; but then presumably his assists should be higher for that.
