El Tri notched a 3-0 win over Israel to open their World Cup preparations, but the Manchester United striker said there is still progress to be made.
"We knew it was a very difficult preparation match against a great team, thanks to God we got the triumph," said Hernandez after the game in quotes carried by Record. "We know that there is still a lot to work on."
The 25-year-old's words were echoed by manager Miguel Herrera, who said Israel's system and style offered good preparation for Mexico's first World Cup game against Cameroon on June 13.

"Israel plays very similarly to Cameroon, it has two holding midfielders and one player ahead," said Herrera in the postgame news conference. "They have good players, good prospects."
Herrera also confirmed that goalkeeper Jesus Corona, who was taken to the hospital following an accidental clash with Francisco Rodriguez, has been given the green light and will travel with the team to Dallas, where Mexico faces Ecuador on Saturday.
