Cristiano Ronaldo is more of a hindrance than a help at 41 years of age, but there is little chance of Maritnez dropping him.Spain found their groove against Austria, with Lamine Yamal getting sharper every game. Spain are also yet to concede at the World Cup, so they are our pick to advance from this all-European encounter.Back Spain to win at 17/20 with Sky Bet Best AI prediction: Spain to winUSA vs Belgium: USA to qualifyThe USA are seeking to reach the quarter-finals of the World Cup for the first time since 2002, with Belgium standing in the co-hosts’ way.The Stars and Stripes have had a good tournament so far. They have won three out of four matches, and the defeat by Turkey came in large part because Mauricio Pochettino named a second-string side.Belgium have been less impressive. They showed great character to come from 2-0 down to beat Senegal last time out, with Youri Tielemans notching the winning goal from the penalty spot right at the end of extra time. But Belgium were outplayed for most of that match and Senegal ought to have been out of sight. The Red Devils were not particularly good against Egypt or Iran in the group stage either.The bookies have Belgium down as narrow favourites, but with home advantage behind them, we fancy the USA here – either after 90 minutes, 120 minutes or a penalty shoot-out.Select USA to qualify at 10/11 with Sky Bet Best AI prediction: Over 2.5 goalsArgentina vs Egypt: Egypt to score under 0.5 goalsArgentina suffered a scare in the round of 32, as the defending champions were put through their paces by Cape Verde.The debutants put up an extraordinary display to take Argentina to extra time, but Lionel Messi and co. ultimately squeezed through.Argentina will hope for a more straightforward assignment against Egypt, who required a penalty shoot-out to see off Australia in the last 32.Egypt were less conservative than usual in the group stage, but they reverted to type last time out, even though Australia are not exactly known for their firepower.Hossam Hassan’s team will adopt a similar strategy here. And with Mohamed Salah not fully fit, Egypt will struggle to mount counter-attacks to push Argentina back the other way.A clean sheet is on the cards for Lionel Scaloni’s charges in Atlanta.Choose Egypt to score under 0.5 goals at 4/6 with Sky Bet Best AI prediction: Argentina -1.5 handicapSwitzerland vs Colombia: Under 2.5 goalsOne of Switzerland or Colombia will be in the quarter-finals of the World Cup, and it is easy enough to make a case for either side winning this one.Switzerland eased to a 2-0 victory over Algeria in the round of 32. The introduction to the side of Johan Manzambi has given their attack a little more imagination, while the Swiss have also looked solid of late.Colombia beat Ghana 1-0 in their most recent outing, although the margin of victory should have been wider.Nestor Lorenzo will be slightly concerned by his team’s wastefulness in front of goal, though. Colombia have scored just two goals in their last three matches, despite creating an abundance of opportunities in each of them.Given how high the stakes are in the round of 16, this looks set to be an engaging but low-scoring affair.Go for under 2.5 goals at 4/7 with Sky Bet Best AI prediction: Under 2.5 goalsFrance vs Morocco: Both teams to scoreIn the round of 16, France did well to both find a way past Paraguay’s low block and resist their opponents’ intense provocation.Kylian Mbappe scored the only goal of the game from the penalty spot to send Les Bleus through to the last eight, where Morocco await.The Atlas Lions were not at their best against Canada on Saturday, but their efficient finishing on the counter-attack brought them a 3-0 win.Morocco have scored in every match they have played at this World Cup, while they are now unbeaten in 33 matches.France deserve to be favourites, but Morocco will give them plenty to think about in this rematch of the 2022 semi-final.Tip both teams to score at 4/6 with Sky Bet Best AI prediction: Over 2.5 goalsWorld Cup 2026: More from talkSPORTWorld Cup 2026 Betting offersWorld Cup 2026 Betting tips and predictionsWorld Cup 2026 AI predictionsWorld Cup 2026 Betting guideWorld Cup 2026 Top goalscorer oddsEngland to win World Cup 2026 oddsWorld Cup 2026: Best young player oddsAbout the authorGreg LeaGreg Lea is a freelance football writer from London.
