"We have had enough time to study the Liverpool game," said Vasilev. "Their pair of strikers is in any combination world class, but they can be very dangerous with their second line from which players easily transform into forwards.
"Our defensive line will be the busiest on the night and we must try to ease the pressure as much as we can. Most importantly we must have longer ball possession and to slow the game down as much as possible.
"With a bit of luck on our side, I hope for a good result."
