I also think over 2.5 goals will happen very smoothly into match Cambuur vs Ajax because Ajax is on fire and can make score more than 3 goals against weak team Cambuur easily there.
I do agree with you on your bet.It is nice pick.I still will choose Ajax even odd is low.When An unbeaten team will play against some weak team in that situation @1.29 is still good enough.The returning amount will be less but almost sure in my thinking too.
