Keane says the profile of MLS has definitely grown in Europe.
"There are a lot of players in England that I speak to now, youngish kind of players, that want to come over here and play over here," Keane told reporters last week during an MLS media event at Red Bull Arena. "There are certainly a lot of players who look at this league now with certainly a different opinion than they did a few years ago.
"When I went back (last month) and trained with Tottenham for a couple of weeks, the lads asked questions and stuff like that. That just goes to show you how the league has grown."
