Pádraig Harrington says he is in a negative headspace ahead of this week's PGA Championship, but the Dubliner believes he can still win another major.
Harrington, 54, managed back-to-back Open Championships in 2007 and 2008, with a PGA Championship wedged in between.
Around 18 years after his last major, he tells RTÉ Sport that his game is definitely there, but he has to get into the correct frame of mind if he is to challenge at Aronimink.
"I was pretty positive last week, I seemed to be in good stead, but I kind of got a bit caught up in my routine," he said ahead of Thursday's first round.
"I lost the flow of it so I'm actually as negative as I could be right now.
"I'm a little bit stuck so I'm trying to fight through that. So it's a bit of a battle to get a bit more fluidity into my routine and still focus on what I'm trying to do.
"So there's a little bit of a conflict between those two goals."
Harrington has to go back a decade for his most recent success on one of the main tours, winning the 2016 Portugal Open on the European Tour.
The year before that, he claimed the PGA Tour's Honda Classic after a play-off win over Daniel Berger.
More recently, there has been success on the seniors events on both sides of the Atlantic, with three majors to cap them off.
But Harrington acknowledges that there is a different pressure on his shoulders coming into a weekend like this.
"I enjoy it, I love the competition," he continues.
"I still feel like I can be competitive. It puts me under a little bit more pressure trying to be competitive.
"I will say, if this was a Champions Tour minor, I wouldn't be as stressed about losing my routine.
"I'd be a bit more relaxed about it. It's interesting that I've come here and clearly I feel like I need to be on my very, very best form and I need to feel like everything is perfect.
"That's certainly caught up with me."
And while there's plenty of uncertainty there, Harrington says that he still thinks that it could all come together for him at one of golf's biggest events.
"Yeah, absolutely," he says when he's asked if he can still win a major.
"I just have to make sure I don't believe I need to be perfect to do it. That's not how I would have won in it in 2007, 2008.
"I've got to be just a little bit more comfortable about my game and what I'm doing; I feel like it's very hard.
"When you think you need your A-game, your B-game turns up. When you think you need your B-game, your A-game turns up - you've got to feel comfortable in the environment.
"Coming out one-offs to majors can be a little difficult. Every person I meet this week is a stop, hello and a handshake because I haven't seen them in nine months.
"That can make it a little tougher but we can overcome those things."
