Twelve months on Wawrinka and Murray meet again in the last four after quarter-final victories over Marin Cilic and Kei Nishikori respectively. "It has not always been easy for me here but the last few years have been great". The third was a bit lucky for me, it helped that I was able to break him in his first service games in the last two sets.
Murray worked out of danger after dropping the first set to Nishikori with the 30-year-old finding a way.
'And also, the fact I have, you know, a solid track record, winning tournaments, Grand Slam tournaments, and, you know, that really helps'. "Yeah, for sure, it's gonna be a tough one".
"It's not like I played a great point the next point".
"He played very well (against Karen Khachanov) and he's playing better and better".
After a shaky second serve was dumped long by Nishikori, the eighth seed went completely off the boil and did not win another game in the set.
"But still it was a really, really tough battle".
The third-seeded Halep, who trailed 5-0 in the first set, was down 5-1 in the second.
"He deserves the titles that he's got, but his success doesn't affect how I feel about mine".
