KDB combination with Haaland is superb and even Haaland himself acknowledged it during his interview when he was asked how he manages to score many goals he said "If Kelvin can get the ball to him at the right timing, he is sure nothing will stop him because he has the speed". I also add that not only speed, he has the positioning also and his height and determination all adds together to his greatest.
It doesn't mean that if Kelvin wasn't there he will not score, he will still score but not as high as he is scoring when Kelvin feeds him.
Over 3.5 goals is the average Manchester City scores, but I don't play that option in bet. Instead of betting over 3.5goals in the whole match, you can go for 2HT over 1.5 it will have a better odd.
This is something that is really good in my opinion for City because indeed their players believe in each other so it is not difficult for them to find chemistry when they believe in each other.
Now it's not really that difficult, when things like this are already in the players' minds, the victory will continue to be repeated again and again.
