#2 Cracks in defence
Manchester United shot-stopper David de Gea is arguably one of the best goalkeepers in the world at the moment, but the 27-year-old hasn't enjoyed the best start to the tournament and last night's game didn't make things any easier for him.
A silly mix up between Iniesta and Sergio Ramos handed Boutaib a ridiculous one on one situation with de Gea, and even the best goalkeepers in the world can't always deal with such scenarios on their own.
The second of Morocco's goals came via a superb header that no keeper in the world could've stopped, but if the likes of Ramos and Gerard Pique can't ward off such threats against a side like Morocco, do Spain stand a chance against the bigger sides and more prolific attackers?
Now, it's fair to say that Hierro and his side would've looked to play a relatively less intense game in a bid to avoid bookings, but perhaps last night's performance was a little too lackadaisical. A similar performance against any of the bigger sides could cost them dearly.
In 3 group games, Spain have conceded 5 goals - just 1 fewer than the number of goals they've scored. While they may have made up for it yesterday, such mistakes could definitely come back to haunt them against the bigger sides in the knockout stages of the tournament.
Despite boasting of one of the best defensive outfits in the competition, Spain simply haven't been solid enough at the back, and that's something Fernando Hierro will desperately have to address going into the knockout stages of the tournament.
