Jose Mourinho may have been boosted by the return to training of several key defensive members of his Manchester United squad but the main absence will surely be felt up front where there is a Zlatan Ibrahimovic shaped void for the tournament favourites.
What that does do though, is present something of a more open betting heat in the first scorer market and dabbelbet's "Win More when Both Teams Score" promotion is an ideal complement to this punting puzzle.
That's because if both teams score, the online bookmaker pay out a huge 25% cash boost on the winnings of first/last goalscorer or correct score bets in all Champions League and Europa League games, plus every match in the top four divisions of England and Scotland too, including the play-offs. This offer is open to all customers, not just new ones.
Additional winnings are paid out in cash, no free bets or rollover requirements, just 25% extra on the winnings part of your bet , added directly in your account balance, up to £100 per game. Full terms and conditions here .
Celta have seen both teams score in four of their last five Europa League home games and United have kept only two clean sheets in six European away days this season so goals could well be on the agenda.
Fancy Marcus Rashford to step up and break the deadlock for his side? The England international is priced at 4/1 (5.0) but with this offer, should he score first, the winnings would be automatically boosted by 25% if both teams find the net.
What about Henrikh Mkhitaryan? He's been brilliant for United in this competition since arriving at Old Trafford, netting five times thus far, and at 13/2 (7.50) to net first, a £10 bet would return £75. With this offer though, if BTTS lands, that payout would be up to £91.25! Based on the "winnings" part of the bet (excluding stake) being £65, plus an additional 25% equating to £26.25.
Here's how some of the other first goalscorer pay-outs would look should both teams register in Vigo.
The same 25% is applied to correct score picks too, so a 1-1 draw which is currently priced at 5/1 (6.0) would be subject to a further boost of 25% on the winnings part of the bet.
