Iago Aspas scored a stoppage-time equaliser - with the aid of VAR - as Spain scraped an unconvincing draw with Morocco to top Group B and secure a World Cup last-16 tie against hosts Russia.

Youssef En-Nesyri - who plays in Spain for Malaga - looked to have won it for Herve Renard's side when he powered in a superb header from fellow substitute Faycal Fajr's corner.

But Aspas flicked in Dani Carvajal's low cross to make it 2-2, with referee Ravshan Irmatov initially disallowing the goal before overturning the decision.

Spain won the group on goals scored as Portugal were held to a 1-1 draw by Iran - but had a tough night as they extended their unbeaten run to 23 games.

A dreadful mix-up between Andres Iniesta and Sergio Ramos had allowed Khalid Boutaib to stride through and give Morocco a surprise 14th-minute lead.

Iniesta made amends five minutes later by helping create a sublime equaliser, exchanging passes with Diego Costa and getting to the byeline before cutting back for Isco to steer high into the net.

But Spain looked wobbly in defence when pressed by a committed, aggressive Morocco side, with Boutaib denied by the legs of David de Gea after Hakim Ziyech's quick throw sent him clear.

Nordin Amrabat was desperately unlucky not to score in the second half as his searing shot came back off the angle of post and bar with De Gea motionless.

Isco was denied a second goal when his header was diverted wide by Romain Saiss - playing instead of dropped captain Medhi Benatia - before the late drama.

Spain wobble at the back

Spain have been hit and miss at this World Cup - perhaps unsurprisingly, given the turbulence surrounding the pre-tournament sacking of coach Julen Lopetegui.

They were excellent in their opening game against Portugal - but had to settle for a 3-3 draw - and poor in their second match against Iran - but won 1-0.

In Kaliningrad, they dominated possession - having more than 75% of the ball - and had 18 shots to Morocco's six. However, they produced a performance that must still have concerned new coach Fernando Hierro.

The game's first two goals were the clearest demonstration of Spain's strange display. Iniesta's loose return pass to Ramos was down to a lapse in concentration, allowing Morocco to take the lead, but his setting up of Isco's equaliser was beautifully done.

Spain were defensively off-key whenever under pressure, with Gerard Pique lucky to escape punishment early on for a two-footed lunge towards Boutaib - saved by the fact that he did make contact with the ball - before he avoided sanction for a clear second-half handball on the edge of his own penalty area.

In Pique's defence, he nearly made amends with a header that veered just wide, from an Isco corner, but they were grateful to Aspas for securing them first place in the group - and ensuring they avoided the dangerous Uruguay in the next round.

Morocco make their point

There is a strong case for arguing that Morocco are the unluckiest team to be eliminated at the group stage - with poor finishing costing them a point against Portugal, and possibly all three against Iran.

As it was, they lost both of those games 1-0, meaning they were already out before they kicked off against Spain.

There has clearly been a lot of frustration building up in the Morocco camp in recent days - with captain Benatia making public criticisms of assistant coach Mustapha Hadji, the former Coventry midfielder, after Wednesday's defeat by Portugal.

That may have contributed to Benatia being left out of the team to face Spain - but those who did play went into the match with a point to prove.

At times, they were too aggressive - as a tally of six yellow cards showed, even if one or two of them were harsh.

However, their commitment made for an enthralling game in which they defended with great discipline and looked dangerous on the counter-attack.

Renard had complained before the game about refereeing decisions going against his team in their opening two games, and his players thought they had been on the wrong end of a decision when Aspas' goal was allowed to stand.

Frustrations threatened to boil over in a chaotic end to the game, with a cluster of players being involved in a confrontation - although television evidence suggested that referee Irmatov did get it right by allowing the goal after consulting with the video assistant refereeing team.

Man of the match - Nordin Amrabat (Morocco)

Now we are facing the moment of truth' - what they said

Morocco coach Herve Renard: "We suffered, as every team that plays against Spain suffers, because their line-up is a mix of Real Madrid and Barcelona players - all exceptional.

"But I think our players, the whole team, should be commended for this game and the entire World Cup.

"We've lacked a bit of experience and there were games we should have had better results in. But we've shown that we can take on two of the best teams in the world, Portugal and Spain, and represent Morocco well."

Spain midfielder Isco: "Now we are facing the moment of truth but I have complete faith in this team.

"Morocco was a really tough match. Maybe we were lacking greater control of the game and normally that is what we do a lot better."

On facing Russia in the last 16: "It's going to be a tough game. They have the whole country behind them and play excellent football. We played a friendly against them ahead of the World Cup so we know about them."
