Ronaldo at Real Madrid, meanwhile, has toiled with the 33-year-old struggling to scale his usual lofty heights.
One of the Argentinian's most forgettable moments happened back in 2012, during the Champions League semi-final clash against Chelsea.
The Chilean forward also spoke about how players are unfairly judged by their price tags and their wages.
Speaking to Sky Sports, Manchester United star Sanchez - who left Barca for Arsenal in 2014 - said: 'I think football saves many people. He also revealed that to live a luxurious life you need to put in a lot of effort as a footballer.
He said: "Sometimes people say things such as, "He's got too big for his boots" or say, "He's changed". You buy a flash auto and people say that you're a show-off." he told Sky Sports.
Sanchez goes on to explain how you can't please everyone when it comes to your actions, but he enjoys himself and just tries to be happy. I've learned so much over time and with the experience that I've gained. "People don't see that".
The duo have both been in sensational form this season, living up their billing as two of the best players in world football. Sanchez reportedly earns £350,000 a week at Manchester United and says that financial-based criticism is unwarranted.
