The 23-year-old is on loan at Upton Park from Inter Milan and has made an impressive impact with the Hammers, his pace and power troubling defences.
As West Ham prepare to travel to Arsenal this weekend, Behrami believes that Obinna is the key to getting something from the Gunners.
Behrami is quoted in the Daily Mirror, saying “Everyone will fear playing Victor, especially one on one. He is an unbelievable player and can score every time he is given a chance. He is a very good striker and what we need.
“But it is not only him. I think now we just need positivity, passion and I think we can get out of this situation.”
Swiss international Behrami is confident that if they are at their best, West Ham can get a result at Arsenal.
He continued, “It is very difficult if you don’t go to play. But we did well against Arsenal home and away in the last two years so we are positive.
“If we keep going like we did in the second half against Stoke and in extra-time I’m sure we can get a good result.”
