Senegal boss Aliou Cisse admitted he was left frustrated by his side's failure to hold onto the lead against Japan on Sunday.
The Lions of Teranga took the lead twice during the match through Sadio Mane and Moussa Wague, but were pegged back both times as Japan clung on to claim a point.
Speaking in his post-match press conference (via ESPN), Cisse said: “Of course we have regrets.
“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.
