Man Utd striker Owen says jury out on Hernandez
Hernandez has looked sensational in two cameo appearances against Chelsea and Newcastle.
But Owen said: "The fans are obviously really excited about the new signings, especially Javier.
"It'll be interesting to see how he settles down.
"It is difficult to come from foreign countries with the different food and weather, particularly around the turn of the year when it's freezing. But so far, so good."
