Hull City goalkeeper Allan McGregor has admitted that the Europa League qualifiers could be tricky, especially if the club have to travel a long distance.
The Premier League side have been drawn against either AS Trencin of Slovakia or FK Vojvodina from Serbia, with McGregor saying that unknown sides can cause problems.
"It really depends where the draw sends you and I had the best of both worlds," he told BBC Sport.
"I've experienced qualifying and not qualifying and it's definitely difficult to go away to some of these places."
Trencin are 4-0 to the good after the first leg against Vojvodina.
