The ex-Manchester United striker says he has been impressed by the league's recent growth.
The 36-year-old Uruguayan, who is currently playing for boyhood club Penarol, has often been linked with MLS in the past and was rumoured to be heading to North America last winter after announcing his plans to leave Japanese side Cerezo Osaka.
Colorado Rapids technical director Paul Bravo even revealed at the time that the club had been offered the chance to sign the 112-times capped forward but added that talks never got serious.
“Diego Forlán — did we have a conversation about him? Yes, we did,” Bravo told the Denver Post. “But it’s probably the same conversation 10 other clubs in this league have had in that same time frame.
“He was a guy that was offered up to us. I wouldn’t go beyond that. Everybody gets these players thrown out.”
Nevertheless, Forlan is still open to the idea of a spell in MLS after seeing how much the league has grown of late, telling Deporte Total USA: “You see on television that MLS is a tournament that attracts attention and the level of football has grown a lot. I still have not had an offer to come but we'll see."
At this stage of his career, it remains to be seen what kind of production Forlan could offer an MLS club, but his past achievements would at least make him a headline-grabbing signing.
The veteran striker has taken in spells at big-name clubs like United, Villarreal, Atletico Madrid and Inter Milan during his decorated career and finished as top scorer in La Liga on two occasions, while also winning the Premier League, FA Cup and Europa League.
In addition, the Uruguayan, who retired from international football in March, led his country to the 2011 Copa America title and a surprise fourth-place finish at the 2010 World Cup, where he took home the Golden Ball award for the tournament’s best player after netting five goals.
