Bayern Munich booked their place in the Champions League semi-finals by humiliating Barcelona on Friday night.

The Bundesliga champions breezed past their Spanish opposition, winning 8-2.

It's Barca's worst defeat since 1943 and following the result, Gerard Pique admitted that the club have hit 'rock bottom'.

"It was a horrible game, the feeling is terrible...embarrassing is the word. I think now we have hit rock bottom," he said.

He's not wrong, either. A brace from Thomas Muller, plus goals from Ivan Perisic and Serge Gnabry gave Bayern a 4-1 lead at half-time.

Joshua Kimmich and Robert Lewandowski added two more after the break and salt was truly rubbed into the wounds when loanee Philippe Coutinho rounded off the win with a brace.

He refused to celebrate either goal against his parent club, but the damage was done.

In fact, Barcelona could be left even further humiliated if Bayern go on to win the Champions League. 

According to The Mirror, they face the embarrassing prospect of having to pay Liverpool €5m (£4.5m) if Coutinho gets his hands on the trophy this season.

The Blaugrana paid a massive £142m to secure the Brazilian's signature back in 2018 and a number of add-ons were inserted into his deal.

One of the clauses says that Barca will have to pay Liverpool £4.5m if Coutinho wins the Champions League in the 2018/19 or 2019/20 season. 

Incredibly, the clause is specific to the player, not the club, so if Coutinho lifts the trophy with Bayern while on-loan, the Catalan giants still have to pay. 

How humiliating. Those in Barcelona's boardroom will certainly be sweating now because it looks like no one can stop Hansi Flick's team right now.

That £142m move for Coutinho looks even worse now, doesn't it?
