Senegal coach Aliou Cisse has admitted that his side played poorly in their Group H clash against Japan on Sunday.
The West African side drew 2-2 to Japan in Yekaterinburg, following goals from Sadio Mane and Moussa Wague for Senegal and Takashi Inui and Keisuke Honda for the Samurai Blue.
Despite being top of the group, level with today's opponents, Cisse insists that his side have more to offer than their performance at the weekend.
"Of course we have regrets," Cisse told reporters.
"We must acknowledge that we didn't see a great Senegalese performance tonight in comparison to the match against Poland. We were not very good frankly, and Japan were the better team, I have to admit that.
"But despite that fact, we led twice and what's annoying for me is the two goals we conceded. Japan played as expected; they are a very technical team with such good quality in that respect. We pressured them well at the start and they made some errors, which we exploited. But as soon as gave them some space, it became difficult for us. Now we have to hope for the best when we face Colombia. "
Both sides are unbeaten in their World Cup campaign in Russia, with only the number of yellow cards separating the two teams in their group.
