This dude is incredible. In an absolutely tragic team, he has managed to pull out 23 goals in all competitions, and he could still add more. For context, this is the same as in 06/07, which was he real breakthrough season. I'm willing to bet that at least 20 of those directly impacted the results of the game - either by being opening goals, game winners, equalizers, etc. I mean he has two hattricks in 3-2 wins, FFS. On top of that he shows more desire and leadership than the rest of the team combined. He actually cares.
He certainly hasn't been perfect all the way through, but to suggest in any way he has been a liability to this team is a massive insult.
Edit: To further elaborate on his goal tally, this is his second best goals/games ratio season for us by some margin above 06/07 and 08/09.
