British number one Andy Murray has praised the contribution of Ivan Lendl since taking over as his coach in January.
The eight-time Grand Slam winner was appointed as the Scot's coach after he parted company with Alex Corretja.
The former number one helped Murray to the Wimbledon final on Sunday, and the 25-year-old has praised the impact that the Czech Republic-born mentor has had on his career so far.
"He is a massive help, especially when it comes to keeping cool, dealing with high-pressure situations and managing tough moments during important matches," wrote Murray in his BBC Sport column.
"He's made a big difference in the way I prepare for the majors, which is something I felt I needed or was maybe missing. Things are going in the right direction, but there's much more to come.
"Hopefully we'll start to see that when I come back to Wimbledon for the Olympics. Sunday was painful, but the prospect of attempting to win a gold medal is already spurring me on."
Murray lost in four sets Roger Federer at SW19 on Sunday and is still in search of his first Grand Slam crown.
