Andy Murray admitted Jerzy Janowicz had provided an extremely awkward test as he overcame the Pole in four sets to reach a second consecutive Wimbledon final.
The British No 1 had to dig deep against the 24th seed, coming from a set down to claim a hard-fought victory that secured him a shot at Novak Djokovic in the final.
Murray acknowledged that Janowicz's mammoth serve and extreme all-court power posed him some severe problems and was delighted to eventually see off the rising 22-year-old star.
"It was a very tough match today, completely different to any of the other matches I played so far," the Scot stated. "He is a very talented and unpredictable player.
"He hit some huge serves out there and gave me very little rhythm. I am glad to get it done."
Murray will face an even stiffer challenge in Sunday's final, though, with world number one Djokovic underlining his undoubted class with a thrilling five-set win over Juan Martin Del Potro.
The Briton will be hoping his Serbian rival feels the effects of what was a record-breaking semi-final marathon, although he conceded he was hugely impressed by what he had witnessed.
"It will be a tough match, him and Del Potro played an incredible match today and I saw some of the stuff they played, there were some great rallies," he continued.
"Novak was moving very well and it will be tough, I have played him once on grass at the Olympics last year [when Murray won] so I will take that thought into my head when I play him on Sunday."
Murray said he felt different emotions to the ones he experienced last year when he won in the semi-final against Jo-Wilfried Tsonga.
"It is very different to last year," the world number two added. "I think this year has been a little bit different for me because there is a lot of expectations, I was almost expected to get to the final this year.
"Last year when I won my semi I was very emotional and today I was just delighted to come through and get another chance at playing in a Wimbledon final."
