I agree that Barcelona is not stronger than Real Madrid, because the quality of the players that Barcelona and Real Madrid have are equally good.
So both have the same chance to win La Liga title.
Yep, both Barcelona and Real Madrid players have quality players. We cannot underestimate one of them, both will have the same chance to win if they play in El Classico. The winning team must depend on which team are ready for the next match. And also how the coach can choose the most appropriate strategy and motivate the players to play with a big spirit to win. The first El Classico in this season should be an interesting match to see because the winner in EL Classico may improve their player's motivation to play better in the next matches.
You are right . Barca and Real both are giant club on LA Liga . The players of both the teams areof the equal quality . We can not call anyone bad . I think El Classico's victory depends a lot on the mentality of the players . If they perform well in previous matches then they are much stronger mentality . Again it is also depends on the skill of the coach . Since the players of both the teams are good , the coach of the team who can use the players appropriately and adopt good tactics will win .
