Huge chance early on for the home side, Dawson's mistake letting in Ondrasek who fires narrowly wide.
Spurs kick us off then, shooting from left to right.
Knut Olav Halseth is the final fan in just before kick-off: "Tottenham should win this easily. Remember, Tromso finished next-to-bottom in Norway and were relegated and Spurs should win with at least three goals to please those Norwegian Spurs fans who has come to Tromso to see their heroes."
Sky Bet make Tottenham heavy favourites to win tonight at 1/3 with Tromso 10/1 and the draw 4/1. Spurs, who are 6/1 to win the competition, enjoyed a 3-0 win in the reverse fixture and are 15/2 to repeat that result while Roberto Soldado is the 7/2 favourite to open the scoring.
Chris Green is next in: "No game in European competition is easy, but if Spurs can improve on last Sunday's nightmare mauling at the hands of Manchester City, then I am sure they'll progress through this testing assignment unscathed."
Stuart has e-mailed in with a short and sweet message for Spurs tonight: "Pure and simple lets just get back to winnings way. COYS"

Tromso: Benny, William, Adnan, Jaroslaw, Ruben, Magnus, KB Thomas, Remi, D Thomas, Morten, Zdenek. Subs: Bakkelund, Norbye, Antonsen, Helmke, Johnsen, Johnsen, Espejord.

@ty_harman is eyeing a dominant Spurs performance this evening: "Disappointed that the likes of Adebayor have been left behind, but then Soldado needs the confidence. Let's go 443 and really go for it tonight."

Spurs boss Andre Villas-Boas has come under incredible pressure in the past week or so, following a 6-0 drubbing at Manchester City last weekend. He has publicly stated that his position as manager is secure despite increasing calls for him to go, so can the Europa League act as a welcome reprieve?
The visitors, Spurs, on the other hand, are one of just three teams who have a perfect record, with four wins from four so far. Of course, with qualification already secured, the temptation to rest key players will be there tonight, but a strong side will surely still be fielded.
You could be forgiven for going into this match thinking that there will only be one winner, looking at the records so far. Tromso are, as yet, without a win in this year's group stages, with just one point to their name so far.
Hello and welcome to commentary on this evening's Europa League Group K clash between Tromso and Tottenham.
