Bayern's victory against Union Berlin last night ended in drama. Dier made his Bayern debut in the second half as a substitute for injured Dayott Upamecano.
Bayern took the lead in the opening seconds of the second half when Rafael Guerreiro grabbed a rebound to score.
A few minutes later, Harry Kane's record-breaking goal was ruled offside.
The game didn't end there, as Sane was slapped in the face by Union Berlin manager Nenad Bijelica – who was eventually sent off – and an altercation broke out on the sideline. Here's a summary of this chaotic game.
Unable to deliver a lethal pass in attack
One thing that was clear in this game was that Bayern were unable to put the ball into the danger zone. This was especially evident in the first half, where Bayern's forwards were unable to get the ball to the right players in the box.
Bayern seem to prefer to attack from distance or with crosses, but both are very bad.
Yes, Union Berlin did unbelievably recalibrate the backline repeatedly and relentlessly pressed Bayern and stifled Bayern's attack – but they are in 15th place in the Bundesliga for a reason, and as Bayern Munich you have to expect more.
"Harry, catch the ball!" – Bayern need to pass the ball to Harry Kane more often
Bayern lack players who run behind the backline. As a result, through balls become less common. Kane's goalscoring ability masks this nicely now, but the problem becomes more and more evident as passes to Bayern's main players drop.
But why didn't the ball get to Kane? It's not a question of the ability to create chances, it's the players who keep choosing to shoot or cross from difficult positions outside the box.
None of Bayern's wingers have the ability to cross, which is unfortunate. Kingsley Koeman's performance tonight was a disaster, with no cross on his nine attempts. Sane too.
The striker just had to find Kane and see what Kane did when he got the ball – two shots: one on the crossbar and then converted into a goal by Guerrero and another into the back corner of the net, but it was ruled offside.
There have been improvements, but there are still many deficiencies
After the defeat in their last game, the players did not show the fighting spirit and passion that one would expect from the Bayern team. This is disappointing, but it has become a common trend these days.
Yes, manager Thomas Tuchel made some important changes, such as moving Leroy Sane back to the right and pushing Guerreiro to left-back – both of whom were outstanding. Bayern also fended off the never-ending pressure of Union Berlin well. But that's not the reaction you're expecting. There is still a lot to improve tactically, as the team still lacks a clear game plan.
If Tuchel doesn't want to be sacked, he still has a lot of work to do.
