"Atletico are a tough draw, but we've got enough to get through," said Thompson.
"We have the know-how and the knowledge to get through this group - I can't see it being a problem.
"We know about PSV and Marseille and I can't see a problem there. Atletico, yes, that'll be difficult but we will go through.
"The important thing is making a good start. We took one point from the first three games last season and we've got to do better."
