Ofcourse,this is transfer window,every team is looking at adding players to their squad, Leverkusen did well last season,but that isn't enough reason not to sign single player or never sign a player at all,just saying,but if Leverkusen does not sign players,it will be difficult for them to win the league again especially now that Bayern Munich have started signing players that they assume can take them to the level they want.We will 'all see If Leverkusen will be able to retain their tittle or they will let it slip away from them.
Retaining the title is not an easy task and those that do that usually pass a lot of tough times in their way to keep the flag of the club flying high. Bayern Leverkusen can still defend the title even without signing any players, they need to be very observant of other teams and easily adjust their strategy to the one they’ll be using against them by their opponent. If you can counter everything from your opponent and strike back later when they’re weak, it becomes very easier for you to remain in the winning side of the game.
I won’t be putting too much emphasis on Bayern Leverkusen to win the trophy for the second time in a row, but rather let them see how they can strengthen their team to be amongst the top four of the league and always get a spot in the champions league. They can be improving in that direction for the meantime if at all the title league contender or winning it won’t be consistent.
