For those who often bet on football, Im sure you guys ever seen markets that could be said to be abnormal but I dont think its right to call it a trap line.
Because even without cheating - in the end the bookie will always win, but I do agree that sometimes bookmakers provide a strange odds as if they already know the final result.
For example, in the Europa League final last month I posted about this before the match started
UEFA Europa League final today, kinda surprised to see the odds for Leverkusen is still 1.80x considering they are still unbeaten in this season.
I guess the odds for Leverkusen will only range between 1.5x to 1.6x, 1.8x is quite big considering they are the favorite to win the Europa League this season.

I also thought that Leverkusen would win easily against Atalanta, but after checking the odds - I think this match could end in a draw (normal time).
