The betting odds probably were, I've not looked at them and wasn't really thinking of them, either. I was thinking of our odds based historically, both our recent record as a team and broader record as a club.
Our away record this season prior to yesterdays game was Lens (Loss), Sevilla (Win), PSV (Draw), i.e. hardly enough to give you comfort that we would win yesterday.
I was bored at work, so I decided to dive into our away record in Europe after winning the league in 1991 (excluding qualifiers).

We played 136 away games in total resulting in 56 wins, 32 draws, and 48 losses. That gives us a win rate of 41%.
That number was propped up by easy competition in the Cup Winners Cup and Uefa Cup/Europa League.
If you look solely at the Champions League/European Cup.
We played 94 away games resulting 31 wins, 25 draws, and 38 losses. That gives us a win rate of 32%.
I don't know what data betting companies use to determine odds, but I would guess they use domestic form which is about as relevant as to European competition as International football is to club football.
