The Czech Republic midfielder now has seven goals for the season, but he's just happy to do his bit for the side.
“I say every time that it doesn't matter who scores, and I am very happy that I could help my team with the goals," he told the club's website.
“This is a very important win. Today Mikey [Antonio} was very unlucky, he had maybe three chances. I scored today and I hope he will score a couple next time.
“We have a really good team, and we play like a team too, not individual players."
Victory lifted the Hammers up to fourth in the table, temporarily at least, and Souček is determined to keep on experiencing that winning feeling.
“It's nice to be fourth," he added. “We are very happy to be in that position and we want to stay as high as possible because it's still only half-way through the season.
“We will continue to work hard and be prepared for the next game."
