In the future, we prefer only small teams as winners because some of the core players are always reserved to give opportunities to the reserve players.
Football is not only about big names or small names, especially when the performance of big teams is not consistent. Football requires predictions from various aspects, there is a coach's strategy, the players who played in the starting XI, playing schedule and so on. In fact, you also have to see how the opponent's performance from the team you choose to bet on. If you only look at the results of previous matches, of course your bets will lose more often. Because what you do starts with the wrong analysis.
