Andy Murray can build on his second Wimbledon success and win more majors with coach Ivan Lendl by his side, says former Davis Cup player Jamie Baker.
Murray is unbeaten since reuniting with Lendl, following back-to-back titles at Queen's Club and SW19.
The 29-year-old won both of his previous Grand Slams and Olympic gold under the guidance of Lendl.
"With Lendl around, Andy finds this perfect balance of mental state and how to perform at his best," said Baker.
"Lendl being back in the camp is a massive bonus for Andy."
The pair ended a successful two-year arrangement in March 2014.
But Murray reached out to Lendl, an eight-time major winner, following his French Open final loss, which came shortly after a split from coach Amelie Mauresmo.
During Lendl's first spell, Murray won the 2012 US Open and followed that up with his maiden Wimbledon title a year later.
Now the Scot is targeting more Grand Slam glory, saying: "I still feel like my best tennis is ahead of me, that I have an opportunity to win more."
'Still a gap to bridge with Djokovic'
And Baker, a former British number two, thinks his friend can add to his already impressive list of achievements.
"To win Wimbledon twice is incredible," he told BBC Scotland.
"He's been so consistent this year, making the final in all three Grand Slams, he's never done that before.
"Obviously, there is still a gap to bridge with Novak Djokovic, who is still unquestionably the number one player in the world.
"But his whole tennis life is now about how many Grand Slams he can achieve. He has three in the bag and the way he is going means he has serious momentum.
"If he stays fit and healthy over the next two or three years, he's going to be in with a shot at the majors every single time."
Murray, who reached the first of his 11 major finals at the US Open in 2008, endured a frustrating period after back surgery in September 2013.
Form and fitness returned in 2015, reaching the Australian Open final and leading Great Britain to their first Davis Cup victory since 1936.
He returned to number two in the world rankings last October but lost a fifth Australian Open final to Djokovic and was beaten by the Serb again in early June, having reached the final at Roland Garros for the first time.
Green, green grass of home
On Murray's quest for more majors, Baker believes home advantage offers the best bet, although only Pete Sampras, Roger Federer and Andre Agassi (twice) have won Grand Slams in their 30s.
"Let's just think about Wimbledon for a start," he said. "Grass is his favourite surface, with the amount of times he has won at Queen's [a record five titles].
"If his body holds up, you'd think for three or four years more at least, he's going to be a contender.
"His hard court form is great, we know how good he is there, and a great foundation for him over the last couple of years is how many matches he's won on clay.
"I'd never want to say 'he's going to win five or six'.
"He's been putting himself in Grand Slam finals consistently over the years and always giving himself a chance.
"He's going to have a shot at every single one for the next few years."
