Everton boss David Moyes admits he knows little about Europa League opponents Sigma Olomouc.
He said: "They are not (as tough as) Standard Liege, who beat us last season in the UEFA Cup. The European draw is difficult, the Czech side put eight past Aberdeen so I will need to have a chat with Aberdeen manager Mark McGhee about that and what he thinks they are like.
"As yet I don't know a great deal about them. But that will change when I start work on it.
"But they are not Standard Liege, they are not as good as that. At least this will not be as tough as last season, Liege were such a good side to get at this stage.
"But it will still be hard. We have to see whether we are good enough.
"Getting ready for the tie so early in the season is the key. Can we be ready for those two games in time?
"We didn't get past Liege last season but maybe in the end that was one of the reasons we had such a good run to the FA Cup final.
"But every competition we enter we are trying to win it, and that includes the Europa League."
