Javier Hernandez is determined to prove David Sullivan right by being a big hit at West Ham.
Co-chairman Sullivan heaped huge praise on Hernandez following his initial £16m arrival from Bayer Leverkusen, labelling him as “potentially the best player who has ever come to the club”.
And striker Hernandez, 29, said: “It gives [me] a lot of confidence. The only thing you want to prove is that he is right but time will tell.
“I am not scared, I am very glad with this challenge, it is a challenge in a positive way. Hopefully I can be a good signing, the people will be happy with me and please my manager too, that I am ready to help my team and him.”
Hernandez also remains well thought of at old club Manchester United with boss Jose Mourinho saying he would not have sold the Mexican in 2015 if he was in charge.
Hernandez said: “I say thank you for those words. All the people around the world and this sport that speak about myself and qualities, I thank them.
“I am always motivated when a trainer like Mourinho speaks well about me”
Hernandez scored 59 goals in 157 appearances at Old Trafford and insisted: “I have evolved a lot but I prefer to show it rather than talk about it. If I don’t prove it on the pitch, it’d be useless.
“I want to show I am a football player and not just a goalscorer. It’s the striker’s job, I have thankfully I scored a lot of goals and I want to continue that.”
And that is bad news for United who Hernandez will face on his second Premier League debut next month.
“I am going back to my old club on the first game, my old house if you can say. It’ll be very special but I am defending other colours there, I want to help my team get the three points and get the season off on the right foot.”
