A second Wimbledon title is nearing for Andy Murray, and the world number two will be relying on adrenaline to keep his focus high.
Andy Murray is hoping to thrive off adrenaline as he continues his tilt for a second Wimbledon title.
Murray overcame Nick Kyrgios 7-5 6-1 6-4 on Monday to book a place in the quarter-finals, though the Australian came under fire for his lax attitude after losing the first set.
The world number two admitted he found it difficult to concentrate as Kyrgios' intensity dropped in the second set.
However, Murray - the highest seed remaining in the competition following Novak Djokovic's elimination - is looking forward to taking on Jo-Wilfried Tsonga next and hopes the adrenaline from a tight match can help push him into the final four.
"Big matches against the best players turn on fleeting chances, and if you want to win Wimbledon, you have to relish those moments," he said in his BBC Sport column.
"Adrenaline will kick in, and that's a good thing - it helps you concentrate harder, move quicker and react faster.
"When you're feeling good out on court, it's as though you're not going to miss and the other guy is going to have to find something special. That's what the best players do; they make you play those extra balls.
"I like those moments, they help me focus better.
"When nothing's really going on in the match, like in the middle of the second set against Nick, it's much harder to concentrate than at 6-5, 0-30.
"You're aware of the importance of the points, so your mind is right there in the moment.
"I've played Jo-Wilfried Tsonga a couple of times at Wimbledon and they both came down to a few points at key moments, so let's hope the adrenaline pulls me through again on Wednesday."
Murray has reached the final of the Australian and French Opens this year, and he believes age and experience give him better grounding to challenge at the majors.
"When I was younger it was much more difficult to stop myself getting carried away with how I was playing or who I was playing," he continued.
"When I hadn't won a grand slam it was like: 'This is my chance. I might do it.' And then, if it didn't happen, I was gutted.
"Nowadays, I know how difficult these events are to win and I take nothing for granted any more.
"I just try and stay in the moment as best I can and hopefully I can keep doing that for the rest of the tournament, because it's served me well over the years."
