Tottenham have been drawn against Slavia Prague in the last 32 of the UEFA Cup - and Damien Comolli won't underestimate the Czech side.
Although they suffered a 7-0 defeat at the hands of the Gunners, Comolli refused to write off their opponents who they beat in last year's first round.
Comolli said: "We played them last year and know how difficult it was, we won there and at home but it was a tough game especially over there.
"So we know it's difficult, they've had some good results in the Champions League. It is going to be difficult but we knew that before.
"I was at the Emirates. I know their qualities and I think they had a bad day at the Emirates.
"What I remember is they drew against Arsenal at home and they did well against Steaua Bucharest twice."
