Fans have slammed Argentina defender Cristian Romero's performance in the team's incredible 2-1 upset against Saudi Arabia at the 2022 FIFA World Cup today (22 November).The Tottenham Hotspur centre-back was poor as La Albiceleste opened their campaign with a shock defeat. Romero made two clearances, blocked one shot, and made one tackle.He could have done better to defend Saudi Arabia's 49th minute equalizer after Lionel Messi had given Argentina the lead from the spot, 10 minutes into the game. Saleh Al-Shehri turned Romero around and scored with a brilliant shot past Emiliano Martinez. The centre-back could have arguably done better for the second goal as Salem Al-Dawsari scored brilliantly in the 53rd minute past a hapless Argentinian defense and Martinez.The Spurs defender was playing his first game since 26 October, having struggled with an injury this season. He was eventually substituted in the 59th minute for Lisandro Martinez.This was the first time in 11 games La Albiceleste conceded twice with Romero on the pitch, which snapped their 36-game unbeaten run spanning three years. Argentina are touted by many as the favorites, so fans were clearly unhappy with the team's performance, especially Romero's.Here are some fan reactions:🇨🇩 (Munch)@osowxvyyRomero is the worst CB i’ve seen in a while1411115Romero is the worst CB i’ve seen in a whileP™@SemperFiArsenalRomero is one of the most overrated players in the world1375101Romero is one of the most overrated players in the worldPaddy@PaddyArsenalRomero hooked, I’ve been saying for months he’s absolute shit but but but he’s one of the best defenders in the league!!!!23318Romero hooked, I’ve been saying for months he’s absolute shit but but but he’s one of the best defenders in the league!!!!.@utdcynicalRomero’s been awful199157Romero’s been awfulAssna Banta@LondonsRedFbThey were putting Cuti Romero in the Saliba category12724They were putting Cuti Romero in the Saliba category https://t.co/oxBDWLwsiZ𝐉𝐮𝐝𝐝𝐚𝐡 ™🇦🇷@iamjuddahYou can't tell me Romero is better than Lisandro Martinez 23663You can't tell me Romero is better than Lisandro Martinez 😂😂HW@hw1905Romero when he actually has to defend instead of fighting his opponent538Romero when he actually has to defend instead of fighting his opponent https://t.co/0qeuibtLPH𝙂𝘼𝘽𝙀𝘼𝙎𝙏 ✍🏿🇦🇷@AfcGabeastRomero hooked on the hour mark after eating two fat goals against the worst team in the world cup, what a shambolic defender 1145Romero hooked on the hour mark after eating two fat goals against the worst team in the world cup, what a shambolic defender 😭😭Eduardo Hagn@EduardoHagnCuti Romero, the gift that keeps on giving.74739Cuti Romero, the gift that keeps on giving.🇭🇷@killgaspar«cutie» romero clearly the weak spot in this Argentina team, suspect many teams will target him in the knockout stages405«cutie» romero clearly the weak spot in this Argentina team, suspect many teams will target him in the knockout stages"The big favorites never win the World Cups" - Argentina manager Lionel ScaloniAhead of the game against Saudi Arabia, Lionel Scaloni played down La Albiceleste's chances of winning the FIFA World Cup. He said (via Mundo Albiceleste):“The big favourites never win the World Cups. I think that a lot of big nations, great teams, at least eight of them can win this World Cup. The majority are Europeans. It’s what happened in the last years. I think that South American teams couldn’t reach the finals; even in 2014 we did and Argentina maybe could have done a bit better. The rest are just details."He added:"And I think this World Cup will be the same. Details will make champions and not necessarily the team that plays the best."Argentina will next take on Mexico on Saturday (November 26) before locking horns with Poland four days later.
