Tottenham Hotspur boss Mauricio Pochettino says his players should not underestimate Greek side Asteras when the two teams face on Thursday.
Spurs could only manage a draw in their opening two games and will be eager to take all three points from White Hart Lane.
"Asteras is a very good, young team," Pochettino told Spurs TV.
"They won their game against Partizan and drew against Besiktas. They are a good team, very focused.
"They have a very good philosophy on the pitch and have a lot of Argentine players.
"They have a very good side. It will be a very important game.
"Nabil [Bentaleb] is injured but we hope he can get fit as soon as possible."
