They may be struggling for form in La Liga, but Real Madrid showed on Tuesday night that they once again mean business in the Champions League.

Adding to their 3-0 victory over APOEL FC two weeks ago, Los Blancos brushed aside Borussia Dortmund at the Signal Iduna Park 3-1.

Gareth Bale opened the scoring in the 18th minute with a stunning volley, latching on to Dani Carvajal's ball into the box and lashing past Roman Burki.

Cristiano Ronaldo then made it 2-0 five minutes into the second half and later scored a third following Pierre-Emerick Aubameyang's header.

The result finds Real joint-top of Group H but behind Tottenham - who beat APOEL 3-0 thanks to Harry Kane's hat-trick - in alphabetical order.

Ronaldo and Bale stole the show at Signal Iduna Park with their goals but on the whole, Zinedine Zidane's side were much stronger than Dortmund on the night.

That was according to goalkeeper Keylor Navas anyway, with the Costa Rican saying in a post-match interview: "We played a very good match.

"In other games we've unfortunately not been able to finish despite playing well, but we were strong and that's why we won."

Navas, who is one of three nominees for UEFA'S 'The Best FIFA Goalkeeper 2017' award, has made a rocky start to the 2017/18 season but was solid against Dortmund.

"You have to learn from things that do not always go as you want," he added. "Those moments have to be taken with ease knowing that the same mistakes won't be made in the future."

Dortmund managed only four shots on target against Real but when Navas was called upon, he responded. There was nothing he could do about Aubameyang's header, either.

There are rumours that Real will once again try to sign Manchester United's David de Gea in the near future, but the question fans are asking is why?

Navas is a world-class goalkeeper in his own right and, like De Gea, possesses great reflexes and is very good in possession.

The 30-year-old showed as much against Dortmund with a tidy piece of skill to completely fool Aubameyang. Check it out in the video below.

How's that for composure? Navas could have taken the easy way out and punted the ball up the pitch, but he took a risk and it paid off.

Bear in mind that Navas' skill came in the ninth minute with the scores level at 0-0, too. Had Aubameyang intercepted, he would have likely made it 1-0.
