Without luck it's bullshit. Several teams that reached the Champions League final including Real Madrid because to luck. In one season, Real Madrid lost in the first leg in the knockout round, but they were always able to come back when they played at home in the second leg to reach the final. Isn't that luck other than just hard work and team ability?
Yeah. We can say there’s luck because even if both teams try all the possible best they can, if there’s no luck, none of them will win, so anytime the luckiest team wins the match in every match, however, if there’s no luck, none of them will succeed, but at the same time, performance is also another crucial thing we should observe. Even if we put luck in the first place, performance should also be among them because without the ability of the team to score against the other team seriously, they won't, and again, this performance is what will determine how lucky they are to secure the goals.
Something like that never happens every season to the same team, in fact last season Real Madrid had to admit defeat to Manchester City until Manchester City finally won its first title in the Champions League. Luck is part of the result of a game, this includes sports and whatever you do.
Manchester City was the favourite team last season. Manchester City was doing very well last season. Manchester City was a team that whatever strong a team is they will defeat them, as of last season. because they were very strong and they were playing with their full squad last season. Although we can also say this is luck, it was their consistency that they did very well last season.
