Birmingham play host to Nacional after the two teams played out a tentative goalless draw in Portugal seven days ago.
The Blues were unlucky that day as they hit the woodwork three times and will be hoping that home advantage can help them progress to the next round.
Chris Hughton’s men are priced at 9/10 to win on the night in bwin’s 3Way results football betting market and slight favourites at 4/5 to make it through to the group stages.
However, the contrasting preparations for the two sides means Nacional are well-placed to record an upset.
Injuries have ravaged the Championship side and a depleted team lost 3-1 to Middlesbrough at the weekend, while Nacional had their weekend game cancelled to allow them to prepare fully for their visit to England.
That said, the Portuguese team are notoriously bad away from home. They won only five on the road in the league last year and have lost their previous two European away games to Swedish side Hacken and Icelandic team FH, so their odds of 51/20 for the win may not seem too attractive.
If the season so far is anything to go by, then this game is going to be just as tight as the first leg, with one goal likely to be enough to seal progression to the Europa League group stages.
Birmingham have yet to score more than a single goal in a match this season, while Nacional have not scored more than once on their travels.
This means a bet on the game containing fewer than 1.5 goals at 37/20 offers good value.
A successful £25 free bet on there to be fewer than 1.5 goals, available to new customers who sign up for a bwin account, would return £71.25.
Meanwhile, a 1-0 win for Birmingham – perhaps the most likely scoreline – is priced at 25/4.
