The Republic of Ireland international's LA-based compatriot gave him a glowing report on the league ahead of agreeing to join the Colorado Rapids in the summer.
Doyle, 31, is set to join the Colorado Rapids in the summer at the end of his Wolves contract, with the two teams confirming the deal at the end of last week, following several weeks of negotiations.
Appearing on the Rapids Podcast, the Republic of Ireland international spoke of his excitement at his stateside switch and also revealed that his compatriot, who made the move to LA in August 2011, had advised him that it was the right step to take.
"I’ve spoken to Robbie a number of times. Everyone is all very keen to find out about MLS,” said Doyle. “He said in the first few months it is a bit different. In England you get on a bus and you’re basically anywhere in two to three hours, you don’t have to fly anywhere. That’s not the case in America. It’s something to adapt to, and I’ll be fine I’m sure.
"He said it’s not easy, though. He has played everywhere, in different countries and different clubs. He says MLS is just as difficult as anywhere else. He didn’t go there either to enjoy life; he’s gone there to do well and to play well.
“That’s what he’s done, it is exciting. He has given a glowing report when I have spoken with him. Anyone I have spoken to that has played in the MLS has said the same thing. Hopefully I will feel the same way about it in a few months.
"It is just starting to be shown in the UK as well," he continued. "There are a couple of live games a week now. Especially in the last year, it’s become very popular. A few of my teammates here heard I might be going and there is a little interest in everyone. They were all asking about it.
"People see that it is more of an option for players now than it was maybe a few years ago, so it’s exciting. I think it seems to be just on the cusp of big things. I think as big as it is; it’s growing to a new level, so I am delighted to be joining it at an exciting stage."
On how the move to Colorado came about, Doyle added: The opportunity just came up. I was thinking about what I was going to do at the end of this season - I wasn’t sure. I was invited out to have a look by the club, and still wasn’t sure what I was going for.
“Once I got out there and saw the city - Denver itself, and all of the people involved who worked for the club I felt like it was the right thing to do. I’m really excited about it. I just can’t wait to get started.
“I have personal pride to keep my paws in with my international team, Ireland, as well, so I will have to do well in MLS,” he added. “To have a good couple of years in a place with nice scenery is lovely, but I’m not going out to look at the scenery.”
Doyle joined Wolves from Reading in June 2009 for a club-record £6.5 million fee and would go on to score 34 goals in 178 total games during his time at Molineux.
He has fallen out of favour in recent seasons, however, and has just made his first appearance for the club since January 2014 last month after spending the first half of the campaign on loan at Crystal Palace.
The Rapids, meanwhile endured a miserable 2014 in head coach Pablo Mastroeni’s first season in charge, going winless in their last 14 games to finish eighth in the Western Conference – their worst-ever placing.
The team are still looking to end that streak going into 2015, having drawn their first two matches 0-0, and, with main goalscorer Deshorn Brown sold to Norwegian club Valerenga last week, new number nine Doyle can’t turn up soon enough.
Nevertheless, fans shouldn’t expect the 61-times capped Irishman to put up Keane-like numbers, considering his international strike-partner has proven himself one of the league’s greatest-ever signings - grabbing 55 goals in 87 regular-season games to help LA win three MLS Cup titles in four campaigns and claim the 2014 MVP award.
