Player Valuation: £150m
If one player is in exceptional goalscoring form, as Lukaku is, then it's not unusual for his share of his team's goals to be higher than other players - exceptional things tend to be exceptional and as such can cause statistical anomalies. The combined percentages can't hit higher than 100% and one player's unusually high scoring rate will inevitably lower his teammates percentages, that's just how percentages work.
As such I'm not sure what you're trying to prove here. Are you saying that if Lukaku missed a few chances and knocked a few passes astray we'd somehow be a better team?
The fact that Koeman has found a better way of utilising the teams main striker than Martinez could and is more willing to adapt his tactics in accordance with what's available to him and the opposition seems to upset you.
We would be in a lot healthier state looking toward a non-Lukaku future if the scoring and key creation of the 51 goals we've scored this season were spread around more evenly, that's for sure. As it is we are left with an incredible imbalance should he leave.
No other top end PL club is over-exposed to one player than we are.
