Consistency is very important in football. If you are a team aiming for the championship you have to give your best in every game. If Xabi Alonso instills this idea in the team, we can see a much better team and much better football.
Some coaches can bring a lot of positive power to their team. Both the team and the coach need to be in harmony with each other. Xabi Alonso and his team have already achieved this. I think the team's cohesion will increase even more in the upcoming matches.
Bayer Leverkusen matches the same strength with Bayern Munich. You're right, consistency is the only key that will make mediocre club transforming into becoming an elite club. Bayer Leverkusen ranked first this season, they really got some guts to maintain the lead for some weeks. They have one of the best coaches, Xabi Alonso who's not relenting, making sure he knots every area on the pitch. With the present game performance, it will be difficult for any mediocre team to win them, they already know what to expect and they're ready. Xabi Alonso at their peak moment in the present season games.
I think that there will be many clubs who will eye him to be the new coach. Xabi has been successfully changing leverkusen into the new form. I remember when leverkusen was always staying at the bottom caused by the club has no ability to win against other club last season.
Xabi is just able pushing leverkusen who was a mediocre club last season into the one of team with higher chance to win the bundesliga this season.
It will be surprising me a lot of xabi will able to make it winning the trophy this season. Leverkusen was as strong as bayern munchen.
The draw in allianz arena has been also increase leverkusen's confidence. The club will be also playing in europa league as well. I think that this is the last season of xabi in leverkusen as real madrid may target him as a new appointment for the club.
