The Manchester United boss insists that the decision to give the 24-year-old some much-needed rest over the summer was the correct decision, and he is now reaping the rewards.
Rest is something that the striker had not experienced since arriving at Old Trafford due to various international tournaments, and with the Confederations Cup and the Gold Cup coming up in 2013, Ferguson thought it was essential that the youngster got some rest. The Red Devils manager has suggested that resting is the reason that Hernandez was so sharp in midweek, scoring a double in the 3-2 win over Braga.
"The thing that is making the difference is he got a proper rest in the summer," Ferguson told reporters. "It wasn't exhausting in the way it had been in the previous three years. He was tremendous the other night.
"He is such a dedicated footballer and professional in every training session. He's a really terrific player and the good thing is that he is still improving."
The 70-year-old Ferguson now has a number of selection problems on his hands, as he has the likes of Danny Welbeck, Robin van Persie, Wayne Rooney and Chicharito all battling for two places up front. Yet he praised his players' response to the situation.
"It's a good problem to have," Ferguson said continued. "I don't always enjoy it [telling players they're not playing] but it has to be done. In fairness to all the players they've accepted it well and adapted to it. I don't have any great problems other than having to tell one or two of them they're not playing."
