Yes, only one point, so it will not be difficult for Bayer to reduce this gap, there are already 7 points between them and Bayern, which will be much more difficult to reduce and so far I think that Bayern will not allow this to happen, because the level of opponents in the Bundesliga allows them to feel comfortable. But Bayer at the beginning of the season lost a lot of points with teams like Werder, Holstein, Bochum, if you want to defend the champion's title, you need to beat such teams.
In my opinion, Leverkusen should bring in new faces in the second half of the season, new strength can at least increase their chances of continuing to approach Bayern Munich's points, because I see Leverkusen's current players look mediocre, especially in defense, so far Xabi has not been able to strengthen that sector. Only a few players can be relied on on the field.
They really need to bring in more players if they want to be compete well in the title race, they are far from Bayern Munich with 30 points behind but it would have been a different case if they had added more players to the team before the commencement of the season. It is not late to do that now, we are almost half way through the season already and strengthening the squad will help them maintain their performance and secure a spot in the top 4 to appear in next season’s Champions League if they can’t win the league again.
I believe Xavi Alonso has it in mind to add more strength to the team but let’s see how it will end up when the transfer window opens.
