MLS has already attracted former European soccer stars such as Steven Gerrard, Frank Lampard, Kaka, Andrea Pirlo, Didier Drogba or David Villa. Another soccer superstar could join the American League in the next few months.
Manchester United captain Wayne Rooney would find MLS "attractive", according to Portland Timbers owner Merritt Paulson.
Portland Timbers owner Merritt Paulson believes Wayne Rooney would be well suited to the US.
"I would argue he still has some good soccer ahead of him," he told British reporters in Seattle to see the Sounders' 3-1 win over the Timbers on Sunday. "I think he would be a great signing for MLS - 100 per cent MLS would be attractive for him.
"Keeping in mind that is a very talented footballer, who has quality soccer ahead of him, you are not talking about a 34- or 35-year-old [he is 30]. I get excited about the impact he would have in the MLS more than a guy who is coming in later in his career.
"China is a factor, but also players need to determine where they want to play and what is going to be best for their legacy and lifestyle – where they want to live.
"I think America compares really favorably - I wouldn't want to play soccer in Beijing right now. I am not saying that because I don't like China but the air quality issue is something they have to deal with in a sport which requires fitness."
