"I agree with Danny Mills. The change in system may have cost Atletico. It will be interesting to see Diego Simeone's comments.

"In terms of Ronaldo - he is the best player in the world. Sometimes you have to let him do his thing. He is the most important player to Real Madrid."

Matt Mason: Real got gifted that. If Arda Turan was still on the pitch, it would be going to Extra Time right now.

Phil Johnson: PLEASE bring Javier Hernandez back to United. All he does is score goals.

Clayton Donaldson has put Birmingham ahead with seven minutes to go. A dead rubber comes alive.

"I feel the change to formation that Diego Simeone made might have unsettled Atletico's defensive unit. Simeone is undoubtedly a fantastic coach, but did he get that wrong?

"We could almost have had injury time as long as extra-time with all the antics. It happens in Spanish football. I said I thought Real Madrid might edge it - they had the better chances."

Atletico Madrid deserve huge credit for their performances this season but they were rather disappointing tonight. Did they do enough? Or were they happy to play for penalties from the off?

Looking forward to these? The draw is on Friday.

BARCELONA

REAL MADRID

JUVENTUS

BAYERN MUNICH

Some heartache etched into the faces of the Atleti players but their limited approach left them with nowhere to go once Javier Hernandez had put Real ahead. It looked nailed on for a penalty shootout but Hernandez stabbed Real through.

REAL MADRID INTO THE SEMI-FINALS.

JUVENTUS INTO THE LAST FOUR.

Sergio Ramos clears away...

Koke takes out Dani Carvajal - that's a nasty one and that's a booking. Into the last two minutes. Real about to win a derby for the first time this season. At the eighth attempt.

Alvaro Arbeloa - who only came on 90 seconds ago - is booked for booting the ball out. This could yet kick-off, it's ill-tempered as Diego Simeone waves his men up the field.

FIVE MINUTES added on. Real Madrid on their way to the last four. Again.

Jese comes on for Javier Hernandez. Kill some time.

Lfcway (see 85 mins): These are the type of goals Hernandez will score all day long.

Raul Garcia hits a shot over on the spin at the other end. Javier Hernandez goes down with some well-timed cramp, the Mexican will become a hero for Real if that goal takes them through.

"It will be a huge relief for Javier Hernandez. He's had four decent opportunities. Cristiano Ronaldo has been subdued but it was his run which made the goal, they couldn't live with his pace."

GOOOOOOOOOOOOOLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL!!!!!!

Real Madrid get the breakthrough and it is Cristiano Ronaldo who brings the scalpel. He surgically cuts inside the tired defence and squares it for Javier Hernandez. He's missed some chances but that's a tap-in. Huge goal. Huge celebrations.

"That change makes Atletico even more defensive. You just worry, with Mandzukic limping, if Atletico have the players and fitness to get through extra-time. Their formation is almost 5-2-2 now."

It's just hang on now from Atletico. Nobody further forward than 30 yards from their own goal. Peter Crouch or John Hartson [see 77 mins] would both be good options for Real Madrid now...
