One Direction heart-throb Niall Horan has admitted that despite his global fame, he is still too intimidated to approach Manchester United icon Roy Keane. The singer described meeting the legendary midfielder as his "next Everest."Niall is used to the bright lights of stadium tours and rubbing shoulders with Hollywood A-listers, but the world of professional football presents a different kind of pressure. While the 'Slow Hands' singer has successfully transitioned from boyband fame to a solo career, he admits that certain sporting figures still leave him starstruck and, in one specific case, genuinely nervous.The Irish singer opened up about his reluctance to engage with one of the Republic of Ireland's greatest-ever players. Despite his status as a global household name, Horan explained that the aura surrounding Keane is enough to keep him at a distance, even when they occupy the same room.During a interview on RTE 2FM with Tracy Clifford, Niall was asked if he would ever pluck up the courage to say hello to the fiery pundit. "Oh, stop. I mean, he’s the king, isn’t he? You can tell he’s very funny, obviously. He’s probably more relaxed than he lets on," said Niall. However, he was quick to clarify that the ball is firmly in Keane's court if a conversation is ever to happen."Absolutely not. He’d have to come to me and that sounds like that’s not going to happen," the singer added. "I’ve been in the room with him a couple of times. I actually met him a few years ago, but I don’t know if he’d...I met him, like, about 10 years ago at a Champions League game. But no, I’ve still yet to go near him."The irony of the situation wasn't lost on the host, who pointed out that Niall is "besties" with Snoop Dogg but cannot handle a fellow Irishman. He laughed off the comparison, joking: "Literally, '[Maybe Keane thinks] who’s that man [Niall]? Get out of here'. Absolutely nonsense. I don't want to talk to him. Sure what would I be doing talking to him like? ‘Baby’. I love him, he’s a king."When challenged that he has achieved almost everything else in the entertainment industry, the singer gave the daunting task a fitting title. "That's my next Everest," he quipped, acknowledging that the former Sunderland manager remains the ultimate challenge for him.Add GOAL.com as a preferred source on Google to see more of our reportingNiall's love for football is well-documented, with the singer often spotted at major matches and notably supporting Derby County.
