I think Xabi Alonso is one of the few successful coaches who became a coach after becoming a football player. If we count Xavi, who also gave Barça a new tactical advantage, this is a success that has been less in recent years. I look at the extension of the contract by Bayer Leverkusen with certainty. I expect them to have great success this year as well.
Xabi was successful coach for leverkusen to help it leave from relegation zone. it's different personal. Xabi was able changing leverkusen so much. It's not only from the descipline of players, increasing the ball possessions owner by the club through implementing tiki taka to the leverkusen and many more.
I think that if leverkusen gonna be one if strong contender to win the league like bayern or dortmund. As far as i know that if this is also making xabi is also making the club to be even more careful with its defending strategy.
Xabi may have bette squad this year compared with last year. As you can see that xabi already signed during the middle of season and he has no choice to make some transfers caused by the transfer season already closed.
The fact that if xabi may potentially push its club to be able compete in the top place against bayern and dortmund next season.
