The England star and Mexico young gun have formed a great relationship since Chicharito landed at Old Trafford last summer and they will be back on deck together against Bolton this weekend.
Hernandez has had a slow start to the new season after sustaining a heavy concussion in pre-season but he is expected to start at the Reebok Stadium on Saturday in the absence of the injured Danny Welbeck and Rooney can’t wait for him to get back to his goalscoring ways.
"I'm looking forward to him doing the same, if not scoring more goals for us, this season," Rooney told MUTV.
"Of course people know about him now but, if you look at all the top players around the world, people know how they play and it's still difficult to stop them.
"His movement is so good it's difficult to defend against. It won't be easy for players to defend against him whether they know about him or not.
"It's great to have a lad who has just come into the team, who speaks good English and is always smiling."
