Unfortunately I'm not betting on Messi scoring, maybe in the final if there is a odds boost might consider it.
And he scored goal and it was spectacular to watch yesterday match so if you have place bet on him you can get a free spin but we have a chance on the final match also now but as you said will see odds first and then place bet with Messi scoring a goal.It was fun to see Messi going in final.
His teammates is really respect and trust in Messi, so that's why every penalty they will let Messi to shoot. Almost of the free kicks also Messi but he there's no shoots that make a goal until now. This is why betting Messi to score anytime has bigger chance to happen.
This time the odds boost promotion is quite different,
Duelbits offer to double the current odds but we need to bet the first goal scorer. It's risky to be honest and I'm not sure which one will make a score, Mbappe doesn't always to become the first goal scorer. Now the odds for Mbappe is @3.50, that would be @7.00 and followed with Giroud @5.20, that would be @10.40.
