Valencia was a constant threat as the Hammers picked up a 2-2 draw with Manuel Pellegrini’s side at the weekend, and he showed great finishing ability on both his goals.
Valencia now has four goals in his last two matches and he appears to be fully match sharp, after returning from injury.
"We didn’t talk about Enner since the beginning of the season, only because he got injured before the start of the season," Bilic said.
“His quality has always been sky-high and not only goals, everything. His contribution, he’s great in the air, he’s got a great touch and he’s torturing the defences that have to play against him.
“He deserved this kind of performance.”
Valencia’s goalscoring form only goes to help the Hammers look even more threatening.
With Andy Carroll and Diafra Sakho out with injury, Bilic has needed a front man to step up, and Valencia has done so.
The Ecuadorian international has thrived with the service he has been given, and he will want to keep up his run of scoring form.
