Swansea City manager Michael Laudrup has implored his side to maintain a professional mindset in Thursday night's Europa League playoff qualifier.
The Jacks took out the first leg 5-1 over Romanian side Petrolul Ploiesti at the Liberty Stadium last week but that does not mean they are through to the group stage proper according to Laudrup.
"I have concerns, we will play against a team who have nothing to lose," said the Dane. "They had a huge result go against them last week, losing 5-1.
"So they can just go out and take chances, go forward and try to get an early goal. So we have to be ready from the first minute, that is for sure.
"For a club like us, we want to go on in European competition, into the group stage, so we know we have a job to do.
"Winning 5-1 was a huge result, but once in a while there are miracles and they can happen if you do not have the right attitude.
"But I am confident we will be competitive and try to win the game, not just on aggregate but on the night."
