Ilves failed to take the lead in Luxembourg, and while the expectation is that they will make up for it on home soil, I don't rate the team highly enough to rule out a potential upset where Differdange could win.
Despite the first leg of this tie ending in a 0 - 0 draw, I think this second leg will come alive. Ilves had scored in their last 4 straight matches prior, and differdange also had scored in their last 4 matches prior.
