The £12 million star got his first goals of the season in a recent 3-1 win over Bournemouth after months out through injury.
It was reward for his hard work in twice battling back from injuries which kept him out for the best part of five months on and off.
It was a tough time for the pacy player nicknamed Superman back in his native Ecuador because his strength and spring belie his diminutive stature.
Valencia shot to fame leading up to and during the 2014 World Cup in Brazil with his goalscoring exploits, which included a strike against England in a warm-up game.
Scorer of great goals rather than a great goalscorer
Since joining the Hammers in a big money move from the Mexican league, though, he has been a scorer of great goals rather than a great goalscorer.
He has just six goals in 40 games but has found himself pushed out wide as part of a three man attack for the majority of his time in East London.
Valencia is back to full fitness now and very much Slaven Bilic's leading man at the moment given persistent injuries to strikers Diafra Sakho and Andy Carroll.
Champions League dream
He went on to thank those who helped him through his tough times and admits he dreams of leading the Hammers into the Olympic Stadium as a Champions League team.
"I was never alone.
"I have to keep taking the opportunity; the goal is to try to help the team with the most goals possible.
"It would be a dream to take the team to the Champions League just when we moved to a stadium as spectacular. Although the important thing is (just) to qualify to play in Europe which would give more prestige to the club."
If Bilic's side are to compete for the Champions League places they will need to try and get something from this weekend's clash with rejuvenated Manchester City at Upton Park.
