Young Boys will welcome Slovan Bratislava to Stadion Wankdorf on Wednesday for the second leg of their UEFA Champions League qualifier.A goalless draw between both sides in the first leg last week leaves it all to play for in the return fixture and they will each give their all to ensure progress to the next round.The winner of this tie will take on either Legia Warsaw or Flora Tallinn in the third round of the qualifiers next month.Young Boys returned to domestic action over the weekend and began their title defense with a thrilling 4-3 away victory over Lugano on the opening day of the new campaign.The defending Swiss champions were 3-1 down by the 52nd minute but an injury time winner by USMNT international Theoson Siebatcheu helped Young Boys complete the comeback victory.
