The eight-time Grand Slam victor guided the Scot to victories at the Olympic Games in London and US Open in 2012 and his famous Wimbledon win 12 months later.
Off to the third, and Roanic would try and serve and volley, only the third seed is too good on this point, getting another passing shot - as he grabs the frame 6-4, and leads 2-sets-to-1.
Raonic's last win against Murray came in the Indian Wells Masters in 2014.
1st round: Liam Broady 6-2, 6-3, 6-4; 2nd round: Yen-Hsun Lu 6-3, 6-2, 6-1; 3rd round: John Millman 6-3, 7-5, 6-2; 4th round: Nick Kyrgios 7-5, 6-1, 6-4; Quarterfinal: Jo-Wilfried Tsonga 7-6 (10), 6-1, 3-6, 4-6, 6-1; Semifinal: Tomas Berdych 6-3, 6-3, 6-3.
Having come from two sets down to defeat Marin Cilic in the quarter-finals, Federer lost the first set against Raonic, but found himself on the verge of victory after winning the next two. "So, yeah, that's different", Murray, who won the 2012 US Open against Djokovic, told reporters.
He defeated Raonic on grass last month in the final at Queen's, but said of his fellow finalist: "He's obviously playing probably the best grass-court tennis of his career".
McEnroe joined the Raonic team as a consultant around the same time as Murray's reunion with Lendl.
Murray saved two break points, broke the Berdych serve in the next game and never looked back.
The 29-year-old made just nine unforced errors, in contrast to 30 by the befuddled Berdych, who was powerless to halt Murray's progress to an 11th grand slam final appearance - a milestone which took him ahead of Perry as the British man with the most major finals on his CV.
How that matchup plays out in the Wimbledon final Sunday could go a long way toward determining who wins the championship.
He added: "I have a great opportunity".
Roger Federer lost in the Wimbledon semifinals for the first time in his career, falling to Milos Raonic 6-3, 6-7 (3), 4-6, 7-5, 6-3 on Centre Court.
The Welsh star said: "I'm loving it, it is the best thing ever, We're both thoroughly enjoying being parents and she's wonderful, so it's been the best thing".
After winning Queen's, Murray has been nearly faultless at Wimbledon, dropping just two sets en route to the final, both when allowing Jo-Wilfried Tsonga back into their quarterfinal before displaying great resolve to slam the door and claim victory. "But I helped him so much to get back into that game", he said.
Andy Murray, current Wimbledon 2016 contender, said that tennis has become a distraction from his family life, BBC News reports.
Andy Murray will face Milos Raonic in the final as he aims for his second Wimbledon title.
But the 25-year-old Raonic, the first man from Canada to reach a Grand Slam final, cast aside that break point with a 139 miles per hour service victor. "Unexplainable for me really", he said.
"Now I have an even bigger tool-set to face that challenge on Sunday than I did a few Sundays ago". In addition to being a heavy favorite, Murray will also have his home crowd behind him in this final.
Their semifinals are on Friday at the All England Club.
"Having those experiences in the past, playing against some of the best players of all-time, has helped me a lot".
Raonic, 25, is appearing in his first Grand Slam final. "Very sad about that and angry at myself because never should I allow him to get out of that set that easily", said Federer.
Raonic is friends with former supermodel Heidi Klum, who was in his player's box when he beat Roger Federer in the semi-finals. On the second break point, Raonic stroked a forehand cross-court passing shot victor after both men made hard volleys to stay in the point.
Roger Federer is one win away from his 11th Wimbledon final, while Andy Murray is chasing a spot in the title match for the third time.
