Here, AFP Sports looks at three things we learned from day two at the World Cup.
Portugal takes on Spain in a Group A game in Sochi, Russia, on Friday evening.
"Real Madrid C.F. call for the utmost respect to be shown towards Cristiano Ronaldo, whose conduct has been absolutely exemplary throughout all of his time at our club", the statement previously made on the Real Madrid website reads.
The Real Madrid superstar crashed in an 88th-minute free-kick to earn a point for the European champions in this Group B opener, after a second-half goal from Nacho had put the Spaniards 3-2 ahead.
This will be the first World Cup held in Europe since the 2006 tournament in Germany, and the first to be held in Eastern Europe.
Salah, who has been receiving intensive treatment on a shoulder he injured in the Champions League final, played no part in the match despite Egypt coach Hector Cuper saying beforehand that the Liverpool striker would be involved. "I think football teaches us lessons when we are in hard situations, and I think this is an opportunity for us to grow", he said.
"It wasn't an easy situation, but when you have this extremely good group of young players, and the staff, these excellent professionals, they make your life a lot easier", he said.
Ronaldo joins Miroslav Klose, Uwe Seeler and Pele as the only players who have scored in four World Cups.
But Ronaldo, who became the first player to score in eight consecutive major global tournaments, yet again delivered on the big occasion with his expertly taken set-piece to level for the Euro 2016 winners and inflict more pain on Spain in a chaotic week for the 2010 world champions.
