Legendary winger hails the impact the Mexican striker, who netted after just 36 seconds in the win over Chelsea, has had in his debut Premier League season at Old Trafford
The forward got the scoring under way after just 36 seconds of the Red Devils' 2-1 win over Chelsea on Sunday.
"Twenty goals in his first season is unbelievable," said 37-year-old Giggs.
"You are always in with a chance when you have a goalscorer like Javier in your team. He has made a fantastic impact, on and off the pitch."
Hernandez arrived at United before the World Cup last year from Guadalajara of Mexico for around €7 million, a fee which has looked a bargain this season after 13 league goals and the forging of a promising partnership with Wayne Rooney, with the duo's performances pushing Premier League top scorer Dimitar Berbatov to the bench.
"His English is perfect, which has helped," added Giggs.
"His goal [against Chelsea] just sums up his season.
"Sometimes those chances can come a bit early for you. You are not quite up to speed. Thirty seconds, he gets a chance, he scores. He deserves everything that has been said about him."
