The Teranga Lions bagged their first three points of Group H by a 2-1 triumph at Otkritie Arena in Moscow on Tuesday.
Their challenge is certainly not over as Aliou Cisse's outfit are set to be tested again, this time by the Samurai Blue, before facing Colombia four days later.
“It was unbelievable to get the win. As a team, we played a very hard game against Poland, and we were able to do the job," West Ham midfielder Cheikhou Kouyate, an 87th minute substitute for the Teranga Lions on Tuesday, told his club's official website.
“It’s not finished.
“All games are hard and we just want to continue in the World Cup.
“We have a day’s rest on Wednesday and then we will go again.
"We have another tough game, against Japan.
"It will be a tough game and we need to take points to continue our journey.”
Senegal are making their second appearance at the World Cup.
On their previous outing, the Lions surpassed expectations as they made their way to the quarter-finals before a narrow loss to Turkey at Korea/Japan 2002.
Cisse's side are one of five African teams at this year's World Cup and the only to have avoided defeat so far.
