Saturday saw Der Klassiker as Borussia Dortmund took on Bayern Munich in the Bundesliga.

Dortmund went into clash knowing they would draw level with the Bavarians with victory at the Signal Iduna Park.

However, the home side were left disappointed at Bayern ran out comfortable 3-1 winners.

First-half goals from Arjen Robben and Robert Lewandowski gave Jupp Heynckes side a 2-0 lead at half-time before David Alaba made it 3-0 in the 67th-minute. A late Marc Bartra goal was a mere consolation for Dortmund.

It means Bayern are now six points clear of Dortmund and remain four points ahead of Leipzig who are second.

One reason why Bayern are clear at the top of the league right now is their impressive defence. They’ve conceded eight goals in their 11 Bundesliga matches, less than any other side.

Against Dortmund, centre-back pairing of Mats Hummels and Niklas Sule kept Pierre-Emerick Aubameyang very quiet.

But it wasn’t just Hummels’ defending that was making headlines.

Many eagle-eyed football fans noticed something very strange about the boots he was wearing.

No, not that they were pink and that central defenders should never wear pink boots - although that point does stand - but the fact they had holes in.

What’s wrong with boots with holes in, many of you Sunday League footballers will ask.

Well, when you’re a player of Hummels’ standard with a multi-million deal with Adidas, you expect he can have as many boots as he could possibly want.

So, why the holes?

Why Hummels had holes in his boots

Well, luckily, the defender explained about the match.

"That has no impact," he said of the shoes after the match. "Both toes are a bit injured at the moment. It works that way too.

"Maybe that will be a new model being developed."

So Hummels has got a couple of injured toes so decided to cut a hole in the end of each boot.

That’s the sort of commitment you want from a defender.
