‘I think he is a living iconic figure of Belgian football. One hundred caps, 66 goals, at his age. He has a phenomenal attitude,’ said Belgian manager Roberto Martinez.
‘I hope he can go onto 125 or maybe 150 caps. Sometimes you take for granted what we have.
‘These players don’t come often. I want to give him a big thank you for the commitment he has given the national team over the years.’
Lukaku, who rejoined Chelsea last month in a £98million deal from Inter Milan, seemed emotional as he considered the landmark.
‘I feel very fortunate to be in this position. To be in this generation of Belgian players. We have a good team, a lot of qualities, a very good mentality,’ he said.
‘It’s a very proud moment for me and my family to be added to this list of players who have reached a hundred caps.
‘I hope the next generation understand playing for this Belgium national team is not something you take lightly. You really try to perform and put Belgian football on the map. I am very happy to be in this situation.’
He also batted away suggestions of a rivalry with Cristiano Ronaldo who is the other big Premier League arrival this summer having agree to return to Manchester United.
‘I’ll never compare myself to Ronaldo. He’s one of the three best players of all time,’ said Lukaku. ‘I am proud that I was able to play against him. It’s good for the Premier League that he returns.
‘I don't have a target of goals in my head. I just want to win prizes.’
Earlier, Lukaku revealed he’d appealed directly to Inter manager Simone Inzaghi to allow him to leave even though he was indebted to the Italian club for rescuing his career after a tough time at Manchester United.
