The 24-year-old has been restricted to less than 30 appearances for United this season yet has still managed 16 goals in all competitions.
And Ferguson is keen to warn off any potential offers for Chicharito at the end of the season.
“Javier is on a long-term contract. We won’t be entertaining any interest”, Ferguson said.
“I speak to the players all the time, especially the ones who don’t play. I have said to Javier that it hasn’t been easy to leave him out because of his 16-goal tally.
“If you look at the goals he has scored in terms of the games he has played, he has a brilliant record. He will always have that because he is a fantastic penalty-box player.
“But it’s difficult when you are up against a player of Robin van Persie’s form. Then we’ve got Welbeck, Rooney and Kagawa. That’s the benefit of having a strong squad. It’s given us an advantage.”
Hernandez has been nothing but a revelation since being plucked from Mexican club Guadalajara in a reported £7 million deal in 2010.
After a super World Cup, he scored 20 goals in his debut season at United and became one of a select few players to win the Sir Matt Busby Player of the Year award.
This season, he might not have had as much game time but he still has the best minutes-to-goals ratio in the Premier League which is a real testament to his predatory instincts.
Many have compared his ability from the bench to that of United legend Ole Gunnar Solskjaer and Ferguson is keen to re-iterate the importance of Hernandez to the squad ahead of a Chelsea fixture he is will be playing in.
Ferguson continued: “Ole Gunnar was a very laid-back lad and he could handle not playing every week quite easily.
“Hernandez wants to play in every game. If his patience runs out that isn’t a problem for me. If players aren’t happy that’s great.
“I have no issues with the lad. He’s been brilliant, a breath of fresh air since he came here. He’s a really important player for us.
“He does something in every game. He changes things. He does something different to the other strikers we have.
“Javier will play against Chelsea on Monday because he’s got a fantastic scoring record against them.”
Hernandez has never shown a desire to leave United so far in his career and no fan wants to see him leave. An infectious smile and an unrivalled ability in front of goal have made him a real fans favourite in a short space of time.
With his all-round game dramatically improved this season, Chicharito is becoming a more complete player the more he plays and as he still has his best years ahead of him, United certainly should be doing everything they can to hold on to him.
