In that match I would favor Lazio more than Glimt even though the chances could be the same. But in the Europa League competition I have also seen Lazio's efforts which are not so bad so I would be more confident in Lazio's victory than the home team. Although I would not be surprised if Lazio lost narrowly in today's match at Glimt's home, but I doubt that Glimt can win big in this match even though you say anything can happen in that match.
Anything can happen, but looking at the performance shown by both teams, the match could be tight. It could be a narrow win or even a draw. It all depends on the strategy that both coaches will implement. I hope both of them will not play too cautiously which makes the match boring. There is no team that is really favored, both will have the same chance I think before the match starts. The situation might be different if there is a team that scores a quick goal.
