Willett reached a career high of ninth in the world after claiming the green jacket at Augusta National in 2016, but had slumped outside the top 450 in the Official World Golf Rankings just over two years later after suffering numerous injuries and a loss of form.
Victory in the DP World Tour Championship, Dubai at the end of 2018 proved the 32-year-old was back on track and he was sixth in The Open Championship at Portrush last year before winning the BMW PGA Championship at Wentworth.
Willett’s attention turns to the US PGA Championship at TPC Harding Park, where he finished third in the WGC-Cadillac Match Play in 2015.
Willett topped his group with a 100 per cent record and beat Lee Westwood and Tommy Fleetwood in the knockout stages before succumbing to U.S. Open champion Gary Woodland in the semi-finals and beating Jim Furyk in the third/fourth place play-off.
"It’s always nice to have good memories of good courses and Harding Park is a brilliant course," Willett said.
"For the lads coming from Europe it’s a very similar kind of style, really old, tree-lined; the grasses are going to be bent and rye that we’re used to.
"I was playing well going into the week and I’ve always enjoyed match play. I got on a nice little roll and it was a bit of a shame that I had to play a couple of friends that week which is never nice.
"I had a fantastic week there and it’s a shame it’s going to be without fans but it bodes well for a good week. It’s exciting to be finally playing in a major this year.
"It would be very, very, very beautiful (to win another major). We’ve been practising hard but we all know that golf is a truly strange and fickle game so we’re just going to play, enjoy ourselves and hope to make the most of some nice memories of the course.
At 32, I’m probably in the best shape I’ve been in, no injuries no niggles, and everything has been good
"It would be nice if we could be up there in contention come Sunday."
Willett spent lockdown in Florida with wife Nicole and sons Zach and Noah, a lengthy but enjoyable spell which means Willett is making sure to teach the boys “some Yorkshire English” before they return home so Zach can start school in September.
"I did a lot of work during lockdown on certain moves and they looked pretty but weren’t quite producing the shots that you need to actually play the game,” Willett added.
"It just took a couple of weeks to iron out a few bits and the last couple of tournaments have been quite nice. The body has been as good as it ever has been, that was one of the main things I took from lockdown. I really made sure I worked on the strength and fitness components of what I’m trying to do.
"At 32, I’m probably in the best shape I’ve been in, no injuries no niggles, and everything has been good."
