It will take time for Ten Hag to make changes at Leverkusen because after all the departure of Xabi Alonso has made this team have to go through adjustments. The target next season to compete for the title but it will be difficult to achieve if Leverkusen does not strengthen the team with the swelling of several important players. Everyone associates Ten Hag's failure at Manchester United and maybe many people are pessimistic that Leverkusen under Ten Hag's coaching can be much more successful. Anything can happen but we need to give him time and trust him because who knows he could repeat the success he had at Ajax.
A team like Bayern Leverkusen that have tasted success recently will want to continue to taste it. They failed to win the Bundesliga title last season and lost to Bayern Munich who reclaimed the title from them after they won it from them last season. Bayern Leverkusen may have changed their manager and losing most of their top players to other teams, but we just have to give them some time before we can begin to conclude on how the outcome of the game is going to be. He was more successful at Ajax than he was when he managed Manchester United. But everyone is not getting it right about him now, he may be so poor at Manchester United but it doesn’t mean same will happen in this new club he’d joined now to manage especially when there is high hopes on him to keep the team on high hopes of reviving their good form.
