Fans on Twitter have been left mightily impressed by Cristiano Ronaldo's build-up play in the opening exchanges of Portugal's FIFA World Cup qualifier against Turkey.The Manchester United forward played a key role as the hosts took the lead against Turkey as early as the 15th minute. Cristiano Ronaldo produced a well-timed run to get in behind the visitors' defense to latch onto a perfect pass from Joao Moutinho.After drifting wide towards the right side of the penalty area, the Portugal captain then squared an excellent pass to Diogo Jota with the outside of his foot. Jota dribbled past his man before finding Raphael Guerreiro, who unleashed an attempt from outside the box that hit the woodwork.Luckily for Portugal, the deflection off the frame of the goal fell kindly to Otavio and the midfielder buried it into the back of the net to send the crowd into a delirium of noise.Although it was Otavio who gave the hosts the lead in their crucial World Cup playoff semi-final, fans were quick to notice how the move started with Cristiano Ronaldo.One fan tweeted:"Ronaldo so raw no way people think all he can offer is goals"Here are some of the other reactions after Ronaldo stamped his influence on the World Cup qualifier against Turkey:serg@itsserghoe2ronaldo so raw no way people think all he can offer is goals1:30 AM · Mar 25, 20221ronaldo so raw no way people think all he can offer is goalsAmit Zohar@amitttrmfcRonaldo started that1:30 AM · Mar 25, 2022813Ronaldo started thatNO MORE LIES@generdtionalRonaldo is cooking omds1:31 AM · Mar 25, 2022Ronaldo is cooking omdsNikhil@iNikhilWhat a pre assist by Ronaldo1:31 AM · Mar 25, 2022What a pre assist by RonaldoMoBinta🇬🇲@mobinta10Ronaldo is sharp today yeah like always when he’s playing for selecao nacional1:31 AM · Mar 25, 2022Ronaldo is sharp today yeah like always when he’s playing for selecao nacionalDalotTisticX@CristianoUltraNaah, Cristiano's playmaking ability is so underrated.1:32 AM · Mar 25, 20222Naah, Cristiano's playmaking ability is so underrated.MW@MothapoMWThere is a huge difference on how Ronaldo plays at country vs club level.
