I don't see how you come to the conclusion of taking the ****, seriously I don't.
First Season:
17 goals in 33
Second Season:
5 in 25
Third Season:
11 in 21
This season:
2 in 10
Now I grant the second season was poor, but then I look at Lukaku who is 30m of player and his record this season is shocking, I also take into account 3 managers in that period and when a manger (who again is hated) in Sherwood taps into his strengths he scores goals again. Two seasons of a goal a game and one poor season isn't taking the **** for me or by any stretch and I don't need opinion against fact, that's like arguing on what's the larger number 5 or 20.
In the number of games, you really need to include the ones missed by his own choice - it's his fault he didn't score in them after all.
For reference, that's pretty much all early stage UEFA away games, Feb 13, Aug 13, Dec/Jan 14.
