MLS powerbroker Alexi Lalas insists Liverpool captain Steven Gerrard will not find the competition an easy ride.
Gerrard has signed a two-season deal with LA Galaxy.
"The man is an absolute legend but I also think it's going to be an interesting adventure for him and his family on and off the field," Lalas told Talksport.
"I think it's going to challenge him in a way that he's never been challenged before.
"The Premier League is the most entertaining league in the world, but I would submit to you that the challenges that a player faces would make MLS, in my mind, one of the most competitive leagues in the world."
Lalas added: "The legend label will never go away, but it only gets you so far. After everybody has gotten your autograph and the pictures have been taken you've got to get on the field and you've got to perform.
"Gerrard can be a messenger to the world when he figures out, and it won't take very long, that this is a league that challenges you physically and mentally and, ultimately, is a whole lot better than the perception is out there (England)."
