Cristiano Ronaldo has promised to be a ‘good boy’ as Portugal prepare to face the Republic of Ireland in World Cup qualifying.The Portuguese superstar made some enemies when the two teams last met.Ronaldo missed a penalty in the match, but he had the last laughGetty This was because he celebrated Ruben Neves’ winner in the reverse fixture right in Jake O’Brien’s face.This went down badly with the devastated Republic of Ireland players and the away fans.And ahead of the rematch at the Aviva in Dublin, the Al Nassr star can look forward to a pretty rough reception.Certainly, that is what he is expecting.Speaking ahead of the match, Ronaldo said: “I really like the fans here. The support they give to the national team, it’s lovely. For me, it’s a pleasure to come and play here again.“Of course, it will be tough. I hope they don’t boo me too much tomorrow. I swear that I’m going to try to be a good boy.“But of course, I do my job. I try to win the game and try to score to help my team. I’m sure that the game will be difficult.”In the first fixture, Ronaldo and Portugal were awarded a penalty, which many Republic of Ireland fans thought was down to the 40-year-old influencing the referee.He was denied by penalty hero Caoimhin Kelleher before Neves’ late winner.But Ronaldo denied any suggestion that he had any influence over the referee.Ronaldo’s despair looked like it would cost PortugalGettyBut he had the last laughGetty“It’s normal because they know if they lose tomorrow, they are out, so they try to make things around the game, to try to do things,” Ronaldo said.“But we have to be prepared for a tough game. I think it will be very similar to the game they played in Lisbon – and they have a chance.“They are a good team, so we are prepared. I think Portugal will have a good game and will try to win the match.”What happened?With the Republic of Ireland looking for points in their quest to qualify for the 2026 World Cup, they arrived in Lisbon looking for a point.It had looked like they’d achieved it as well despite seeing Ronaldo hit the post and miss a penalty.The spot kick was awarded after the referee deemed Dara O’Shea to have handled a shot from the edge of the area.Ronaldo stepped up and tried to drive his effort straight down the middle, but as Kelleher dived right, he left his leg trailing and made the save.But as Neves headed home from Trincao’s cross in stoppage time, Ronaldo celebrated in in O’Brien’s face before joining his teammates.It was certainly something that just happened in the heat of the moment, but it will now lead to a spicy atmosphere.
