• e-mail

The World Cup knockout stages have thrown up some wonderful matches so far ahead of England's last 16 clash with Colombia on Tuesday.

Both Cristiano Ronaldo and Lionel Messi were eliminated from the tournament on day 17 after France beat Argentina in a seven-goal thriller while Uruguay bested Portugal to advance into the quarter-finals.

There are, however, some things you may not have known about day 18. Sportsmail brings you 10 things you may have missed from the day's action in Russia.

Croatia sent Denmark crashing out of the World Cup on penalties in Nizhny Novgorod

Peter's proud as punch

After Croatia were awarded a penalty deep into extra time, it looked as if Denmark were heading out with just minutes remaining. 

Ante Rebic rounded Kapser Schmeichel before being fouled in front of an open goal to give Luka Modric the chance to send Croatia into the last eight.

However, the Danish goalkeeper thwarted Modric by comfortably saving the spot kick and sending the game into a penalty shootout.

After the initial spot kick was saved, Kasper's father and legendary goalkeeper, Peter, jumped out of his seat and punched the air with joy following his son's heroics.

Lovely moment.

Croatia and Denmark get off to speedy start 

Croatia's last 16 showdown with Denmark got off to a flyer after both sides scored within four minutes in Nizhny Novgorod.

Mathias Jorgensen broke the deadlock inside a minute before Mario Mandzukic pounced on an unfortunate deflection from the Danes to make it all square early on.

The quick start from the two European sides meant it became the second match in World Cup history to see both sides score inside four minutes, after Argentina's match with Nigeria in 2014.

Lionel Messi broke the deadlock inside three minutes before Ahmed Musa replied just 60 seconds later in their group stage match in Brazil.

However, it slowed down a lot after that 

After their electric start, it seems both Croatia and Denmark took their foot off the gas for remainder of the game.

And it showed. One young fan got so bored of the action that he resorted to entertainment on his phone.

Rumour has it that he was watching the highlights from the France and Argentina game. 

Spain's long wait to beat a host nation goes on

Spain's long wait to beat a host nation at a World Cup goes on after Russia beat Fernando Hierro's men on penalties.

Spain have come up against the host nation five times over four different World Cups, having faced Italy twice in 1934, Brazil in 1950 and South Korea in 2002.

The Italians beat them over two legs in the quarter-finals 84 years ago while Brazil thrashed Spain 6-1 in the semis. 

Sunday's defeat to Russia was the second time Spain were eliminated by the hosts on penalties after South Korea knocked them out of the last eight 16 years ago.

Jordi Alba almost loses his head

It just wasn't Jordi Alba's day against the Russians.

Despite dominating in possession, Spain struggled to break the hosts down in open play and Alba got the ball booted at his head to add insult to injury.

After falling to the ground, the left back sat up waiting for a decision before a Russian player thumped the ball at the back of his head. 

He didn't look pleased.

When you don't have time to complete your fade...

While the game failed to spark into life, one thing that did catch the audience's eye was Sergio Ramos questionable hair cut.

The Spain captain treated himself to a fresh trim for Sunday's game against Russia but it appears he only had enough time to get one side of his head faded.

The dodgy hair cut was slated on social media with some comically attributing Spain's defeat on penalties to the skipper's barnet.

Erokhin becomes first-ever fourth sub at the World Cup

Russia midfielder Aleksandr Erokhin became the first-ever fourth substitute at a World Cup after he came on in the seventh minute of extra time for Daler Kuzyaev.

The new rule came into effect once the last 16 fixtures began on Saturday, allowing teams to make a fourth substitution only in extra time.

FIFA only approved the World Cup could use the fourth substitute rule in March this year, with it's aim to alleviate tiredness and also boost excitement during the two 15-minute halves.

Cherchesov can't bear to watch 

Russia manager Stanislav Cherchesov couldn't bear to watch when Artem Dzyuba stepped up to take a penalty late on in the first half.

The 54-year-old turns away from the action as his striker stepped up to convert the penalty to make it level going into half time.

As the spot kick flew in, Cherchesov's coaching staff leaped off the bench in celebration which then prompted a huge smile from the Russia boss.

Ignashevich makes history... for all the wrong reasons

Sergei Ignashevich made history against Spain after becoming the oldest-ever player to score an own goal at the World Cup at the age of 38 years and 352 days.

Fernando Hierro's side took the lead in the 12th minute after a free kick rebounded off the leg of Ignashevich while he wrestled Sergio Ramos to the ground.

His WWE-like technique would have eventually given Spain a penalty if he had never scored the own goal but his poor bit of defending has now earned him a place in World Cup history.

Russia can't stop scoring own goals

Ignashevich's gaffe in the first half against Spain was Russia's second own goal at the World Cup this tournament.

The host nation become only the second country to score in their own net twice at a World Cup since Bulgaria in 1966.

Denis Cheryshev was Russia's other unfortunate own-goal scorer earlier in the tournament when he netted in the 3-0 defeat to Uruguay.
