Chicharito struck twice in the 3-2 win over Braga to remind Ferguson what he can add to the team going into their clash with Chelsea this weekend.
"Chicharito has given me a good problem," said Sir Alex. "He’s got me thinking, I must say that. He and van Persie and Rooney and Welbeck... I don’t know what to do with them to be honest with you.
"The boy is improving all the time. He has a great enthusiasm for the game, he trains magnificently, he practices all the time and his goal ratio is fantastic.
"It was a great ball from Tom Cleverley for the second goal but Chicharito's movement in behind the defender for the second goal was terrific."
