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.
Leverkusen must realize that defending the title is not easy, currently they are far behind Bayern Munich at the top of the standings with 7 points. Leverkusen this season did not make any player purchases and Xavi Alanso still believes in the old squad. It must also be admitted that Leverkusen this season started the season badly so that they lost points several times, of course this is all because their defense line is not as strong as last season. This is very different from Bayern Munich under Kompany who seems to have a new spirit and even until now Bayern Munich has not been defeated in the Bundesliga.
So I think Leverkusen will not be able to catch up with Bayern Munich's points, because this season Bayern Munich is very difficult to stop. Moreover, Xabi Alanso will leave Leverkusen at the end of the season, of course the management will not bring in new players in the transfer market later. Their target is only to be in second place in the Bundesliga and of course Xabi has a bigger mission in the UCL league, if he succeeds in bringing Leverkusen to the semifinals, of course this will have an impact on his career in the future. especially yesterday they managed to beat Inter Milan very impressively.
