And even though his manne have been boosted by their recent World T20 win this year, the former allrounder reckons the No.1 and third-ranked sides in the 50-over game will be too strong for his team.
He says: “They are number one and three in the world for a reason so we need to get up there and that’s the reason we need to play these teams, so we can see where we are.
“Especially if we beat them, we know we’re somewhere close to them.
“The number one team in the world has to be the favourites going into the tournament but that’s the thing, I don’t think we were favourites in India at the T20 World Cup, so you play the game as you see it.”
The Windies open their campaign against South Africa today in Guyana and face the Aussies on Sunday at the same venue.
But after not playing ODI cricket at the ground for four years, Simmons is not expecting any home advantage for his team.
He says: “I don’t know about home advantage.
“It’s been a while since games have been played here so I don’t know about home advantage.
“Usually you get good wickets here, great outfield, good crowd so it could be a little bit of home advantage.
“But how we do determines which side the crowd gets on.
“Here you can get big scores, chase down big scores and that’s all it is.”
