Olympiakos travel to Turf Moor for the second leg after winning 3-1 last week in the reverse fixture, already putting them ahead in the fight to qualify for the group stage.
The Clarets have just come off the back of a 4-2 defeat to Fulham on Saturday in the league and currently sit in the relegation zone after three games.
Sean Dyche's side need to at least two goals this evening after netting just one away goal, if they are to have any chance of progressing in the European competition, their first since 1967.

Betting & Match Odds
Burnley haven't had the best start to their 2018-19 Premier League campaign, earning just one point out of a possible nine and they will be hoping a win at Turf Moor will boost morale as well as see them advance.
Despite losing the first leg 3-1 to the Greek side, Clarets manager Sean Dyche remains confident in his team and believes they will be able to continue into the group stage of the Europa League.
"They'll be favourites, of course, after the scoreline over there," Dyche told reporters ahead of Thursday's game. "But we've been productive before when the challenge is against us, so that is what we are looking to do."
Burnley's loss in the first leg was their first defeat of this Europa League qualifying campaign, but it was a poor performance, one in which they only had one shot on target - Chris Wood’s first-half penalty.
However, they can take some solace from the fact that Olympiakos have lost 12 of their last 13 away games against English teams in European competition and have never kept a clean sheet away from home against Premier League sides.
