it may appear that all hope is lost for Bayern Munich in the league but they can't give up now until the season is over who knows if Leverkusen will lose 4 matches in the last remaining games and Bayern Munich will catch up with them so they are in similar situations with Arsenal.
Sure Bayern Munich shouldn’t give up, they have to fight till ending of the season, but you know Bayern Leverkusen is not also going to give up till ending of the season. How do you expect a club that haven’t lose any match since the beginning of the season to lose 4 matches continuously? Bayern Leverkusen is currently in first position, with 10 points ahead of Bayern Munich, I don’t think it will be easy for Bayern Munich to take over the first position from them. If Bayern Leverkusen can lose 4 matches, then am sure Bayern Munich will also be losing some matches, no club will keep on winning all their matches, lose will definitely set in.
Bayern Munich will not give up hope that a miracle will happen to them, and Leverkusen will also not just give up by letting them lose so that Bayern Munich can take over their position, that is something that is impossible to happen (Leverkusen gives up to get title), because the title is in front of their eyes now, there are only a few matches left before they can lock in the title this season.
I think there will be many people who want to see Leverkusen maintain what they have done so far, yes there will be many people who will expect them to become champions this season and there will also be many people who want to see Leverkusen set their new record without losing in this season. The reason is that it is very difficult to create an unbeaten record for a full season. And I personally don't remember whether anyone in the Bundesliga has ever done this or not, but what I remember is that no team has been able to record this record in the Bundesliga (correct me if I'm wrong). If they manage to do it then that would be amazing.
