USA qualified for the World Cup knockout stages as Christian Pulisic netted the only goal in a 1-0 win over Iran before the Chelsea winger was taken to hospital injured
In what was a shootout for qualification, it was the USA that relished the jeopardy, playing with great energy and attacking intent as Pulisic bundled home the crucial goal on 38 minutes
The Chelsea man suffered an injury to his hip in that brave action and did not come out for the second half, with the US national team later confirming he had been taken to hospital with a 'pelvic contusion'
Coach Gregg Berhalter said: "He was feeling some dizziness, it was a blow to his abdomen
 We FaceTimed him from the hospital and he was in good spirits
""I sent him a text and checked on him and he said, 'Best believe I'll be ready on Saturday'," also quoted his team-mate Weston McKennie as saying
USA missed his influence as the game wore on but, despite enjoying plenty of territory, Iran could not find the quality to find an equaliser that would have been enough to send them through
USA will now play Netherlands on Saturday at 3pm in the first last-16 game after Louis van Gaal's side secured their spot as Group A winners with victory over hosts Qatar
The onus was on USA to make the running as they knew nothing but a win would be good enough for qualification
 Sergino Dest and Antonee Robinson were playing like wingers rather than full-backs and their intensity out wide set the tone for a barnstorming first half from USA
Timothy Weah was the main beneficiary of the vibrant USA attacks but his composure was lacking at key moments, firstly looping a rushed header from 12 yards straight at Alireza Beiranvand before rushing a finish moments later after some superb play from the lively Josh Sargent
It seemed only a matter of time before the opening goal landed and Pulisic delivered for his country
Weston McKennie sprayed a pass out to Dest, who nodded down for Pulisic in the six-yard box
 He did enough to force the ball home but he collided with Beiranvand in the process and was replaced at the break with a problem to his hip area
Iran had to go for it after the break and Saman Ghoddos set their intent by driving into the back post from a right-wing cross but headed over the bar
Despite lots of possession, Iran struggled to test USA goalkeeper Matt Turner
 The best chance fell to Morteza Pouraliganji, who headed a free-kick agonisingly wide of the post
Desperation started to kick in during the final moments and Mehdi Taremi was adamant he was fouled by Cameron Carter-Vickers but the referee waved away the protests
As the final whistle sounded, the Iran players fell to their knees
 This was USA's day
Was this Dest rampaging down the right flank? Or Cafu? It was hard to tell at times
 The full-back was absolutely key in the way USA pinned Iran back, especially in the first half
 It was his header across goal that provided Pulisic with the opening goal
 The 22-year-old has yet to really kick on with his career at Barcelona, and is currently out on loan at AC Milan, but his raw talent is undeniable
USA manager Gregg Berhalter praises his team for not buckling under pressure of drawing with Iran, a result which would have lead to the USA being knocked out of the group stages of the World Cup:On the evidence of the group stage, pre-World Cup reports of the US' demise appear to have been greatly exaggerated and one thing is for sure - the Netherlands had better not underestimate Gregg Berhalter's side in their last-16 clash on Saturday
The US deservedly overcame Iran in their final Group B clash thanks to a second successive World Cup clean sheet and Christian Pulisic's close-range finish, although the Chelsea forward was injured in the process of scoring and worryingly ahead of the weekend showdown, had to be substituted at half-time
But make no mistake about it, this is a well-drilled outfit, with pace in attack, out wide and in the centre of the park and no shortage of technique to go with that as seen in the impressive displays so far in Qatar from the likes of captain Tyler Adams, Sergino Dest, Yunus Musah, Weston McKennie, Pulisic and Timothy Weah
But while the  are undoubtedly a step up in class from facing Wales and Iran, the US have already shown in holding England to a goalless draw that they are more than capable of mixing it with the so-called Big Boys of international football
So do not be surprised were the US to make life very uncomfortable for Louis van Gaal and Co at the Khalifa International Stadium this weekend, much as they did to much-fancied Belgium the last time they made it through to the World Cup knockouts in 2014
