But it's true. There is stats and history backing this belief. Home teams have an advantage over the visiting teams, the support from the fans cheering all over the stadium and the belief that you're invincible at home gives the players a strong will to get the best result. It is expected that you win every game at home irrespective of your current form or place on the table or your opponent's position in the league.
These statistics only apply to teams that are in top form with impressive records achieved since the beginning of the season, for example, like Leverkusen did last season, bettors have no doubts about placing bets on the home team's victory because they are clearly the favorite team based on their performance and full support from the fans. However, this may not be effective for a team that is in a slump, such as what Manchester United experienced in the Ten Hag era, even though the entire stadium was filled with Manchester United supporters, it would not change the situation, especially if the opponent they faced was a strong team like Liverpool this season.
Concerning the theory of home team having and advantage over the visitors, my take is that it depends on the strength and performance of the home team and who they're playing against, for instance in the Champions League tournament, Manchester City were favourites to win against Sporting Lisbon but then Lisbon have been I'm a very good form this season both in their domestic and international league tournament I think they're currently the only team across Europe that's yet to be unbeaten and they showed class and passion to win against City. Now, if Sporting Lisbon's form this season was poor I doubt if they've been able to match City's energy.Well Amorin is gradually entering the list of best young coaches currently and I believe he's going to instill the winning mentality of Sporting to Manchester United, well it's not going to happen immediately due to the mentality of some players at United but with time and the return of most injured players would boost Amorin's chances of picking a first 11 squad that would help transform United on the long run.
