West Ham are approaching Monday night's Premier League hosting of Leeds flying high in fourth place and Soucek says the clash against Marcelo Bielsa's Whites will provide a measure of just how good the Hammers are.
Soucek also paid a compliment to 11th-placed Leeds by saying that all three of his side's next three fixtures - Leeds at home, Manchester United away and Arsenal at home - were all difficult games.
Furthermore, the 26-year-old Czech midfielder says the upcoming Whites clash is comparable to last month's home fixture against eighth-placed Spurs in which David Moyes' side recorded a 2-1 victory to strengthen their bid for a possible Champions League spot.

"We’re still in a great position, which is really good, so we’re still enjoying our time but we need to be prepared for the next game because this game will again show us how good we are,” Soucek told whufc.com.
“I could compare this game to the game against Tottenham, when we were in this position and we beat Tottenham, so if we do a similar performance and get a win against Leeds, we will be in a great moment and a great position ahead of our games in the future.
“I spoke with the guys, with my teammates, and we want to be in this position at the start of the international break and after the international break we want to carry on.
"If we stay in this position going into the international break we will be happy because we will then have nine games until the end and we will have a good schedule ourselves.
“I hope we do very well in these three difficult matches (against Leeds, Manchester United and Arsenal) and then we will go into the international break with belief and it will set us up for the last step.”
