Ferguson admits he struggles to keep the Mexican out of his team.
"What I'm really pleased with is Chicharito has two, and that puts him up to 14. Wayne got one and Ryan got one, and if we get three or four players around the 20-goal bracket, then we're in business," said Ferguson.
"Chicharito got the break in the summer, the little rest he needed, and you can see the benefit. It's a terrible dilemma when I have that lad there. Sometimes I leave him out to bring in Robin van Persie but as I explained to him, we regard him so highly.
"He is a fantastic professional with an unbelievable attitude to the game. He never stops running or working and every training session is the same. So I'm really pleased for him, and it's good to see Wayne back scoring."
