Xabi is a coach who can learn a lot from a defeat, but it wouldn't be right to expect the same performance as last year. They are the only team in Bundesliga history to become champions without defeat. This shows that there will definitely be defeats in the league, last year's extraordinary performance was an exception. They are one of the championship candidates in Bundesliga again. There will be a tighter competition with Bayern this year.
There is no way we can expect the same performance as last season’s performance from Leverkusen team, they didn’t sign any player to give the squad more strength and depth, they only rely their previous players which will be very hard for the team to achieve the great success they attended last season, and they will be playing in the Champions League and other domestic competitions; they need squad depth to achieve success this season. Nevertheless, they can still do well but the probability is low because Bayern Munich, Dortmond, and other teams have learn from their mistakes and will surely make the competition more tough this time.
