Xabi Alonso has quite a big responsibility in maintaining the performance and consistency of his squad, the threat from Bayern Munich does not play - play and at all costs Xabi Alonso must still maintain the position of his squad at the top of the standings, so the difference of 2 points I think it is still far from safe for Leverkusen, because if Leverkusen slipped in one of the next matches then obviously it was a golden opportunity for Tuchel's squad. We'll see if Leverkusen can be that strong.
Definitely this has to be the toughest part of been at the top of the table, the responsibility becomes even bigger because nat every slightest drop in point, they will be displaced by their biggest rival Bayern Munich who is closely behind them on the league table.
Leverkusen must make sure to continually win their subsequent matches such that they will be points ahead of Bayern Munich but this will be effective if only it turns out Bayern Munich losses their games as Bayern Leverkusen keeps winning but then one of the greatest test Bayern Leverkusen will be facing soonest will have to be that of winning Bayern Munich probably in their next meeting which I anticipate soonest.
