WC qualifying Group G preview
Bosnia-Herzegovina coach Safet Susic believes victory over Greece will give his side an excellent chance of progressing to the 2014 World Cup.
Susic's side have shrugged off their disappointment at losing in last year's European Championship play-offs to Portugal to make a fine start to their new campaign, with big wins over Liechtenstein and Latvia.
But Susic knows the real challenge will come against Greece, who also have two wins to their name but have not impressed in sneaking past Latvia and Lithuania.
Susic told uefa.com: "We have the quality and strength to finish top of the group and qualify automatically for Brazil.
"We have started well with two wins from two, but we are expecting a difficult match in Pireaus.
"We are playing against a major competitor, and if we can get a favourable result our chances of qualifying will increase."
Bosnia have a doubt over Miralem Pjanic, but their problems pale into insignificance compared to Greece, who have lost Lazaros Christodoulopoulos as well as the man he was called up to replace, Kyriakos Papadopoulos. Loukas Vyntras and Giorgios Tzavellas are also out.
Slovakia will hope to put pressure on the top two by recording their second straight win against Latvia in Bratislava.
The Latvians, who remain pointless after two games, will have Juris Sevlakovs in charge as head coach Aleksandrs Starkovs stays at home to recuperate after an appendix operation.
Starkovs said in a statement: "I am convinced the national team will be up to the test in Bratislava."
In the third Group G game, Lithuania look for their first win as they travel to Vaduz to take on Liechtenstein. The hosts have lost both their games so far, including an 8-1 home drubbing by Bosnia in their opening fixture.
