in a match Chelsea v Manchester City I predict that the scores in this match is under 2.5 goals, and I probably would expect Chelsea to win this match, so I'll bet for Chelsea in this match, because I know that Chelsea can beat Manchester City 
Nah man, both teams have a same change to win on this match. And i have bet on Man City ML. But i agree with you on under 2.5 goals, i predict 0-1 win for Man City.
