are not unduly worried about taking on in Sunday's Group H clash despite the Asians possessing plenty of technical quality across the pitch, the African team's coach Aliou Cisse said on Saturday.
Japan defeated 10-man Colombia 2-1 in their opening game, a surprise win that has given Akira Nishino's side a good chance of progressing to the last-16 for only the third time.
“Yes, they have fought hard to be here and their technical ability is above average,” Cisse, whose side joined Japan at the top of the group with a 2-1 win over Poland, told reporters.
“They have passing quality and put pressure on defensively. We have studied them, it will be a tough match... (but) there is nothing that worries me about the Japan team.”
The match, which has been billed as one between Senegal's physicality and Japan's tactical nous, will see the winner reach six points and take a huge step towards qualifying for the knockout stages.
