Don't bet on Leverkusen, bet on Manchester City, Real Madrid or Bayern Munich, I'm sure the winning chance is 70%-80% from all match. Never hope an one season wonder team can be consistent, they're similar like Napoli, in Serie A every teams are not consistent, but Inter is better among other top teams.
Yep. Man City looks more convincing if we consider the chance to win in every match in the whole season.
I'm not sure with Real Madrid and Inter Milan because they started this season with some unexpected results. Meanwhile Bayern Munich, their strength wasn't proven since they just played against mediocre teams in 2 early matches. However, even if Man City looks quite convincing, it doesn't guarantee they will play consistently in the next matches. We need to analyze again how their performance in the next few matches.
You are right, anyone who bets on a football match will see the history of the team they are going to bet on and it is very unlikely that they will continue to side with a football team of course there will be very little chance that they will be able to win the bet they play.
What history?
Most gamblers will learn their current performance or stats. Gamblers will analyze their last few matches.
Sure, it is unlikely to bet on a single team only because the performance of a team can change. Where the teams to play, sometimes also having an impact. If the teams look equal, gamblers often bet on the home team.
