The Irish ace helped the Galaxy take out the past two MLS Cups but he feels the addition of Fabian Espindola to a Red Bulls attacking line which already consists of Thierry Henry and the presence of Tim Cahill will make New York a force this season.
"The Red Bulls (are our biggest threat). They signed the guy from Real Salt Lake, Espindola; I really like him," said Keane.
"And of course they've got Thierry (Henry), and Tim Cahill. I think they're going to be really strong this year."
