Andy Murray has done brilliantly at Wimbledon so far.
He's learned from his defeats really well over the last couple of years and just continued his good work against Viktor Troicki on Saturday to make the final 16.
If you look back at his form in the last year or so, he beat Rafael Nadal in the semi-finals at the US Open last September and he's beaten Roger Federer a few times now.
Murray will be hoping to win his first Grand Slam title in a week's time
And he's taken the world number three spot from Novak Djokovic and made it his own. He's not doing too bad.
Initially there might have been a few seeds of doubt ahead of his first match but his performances in the last two rounds have put him right at the top of the list for this tournament.
Murray is now expected to get to the final - and he fully deserves that status.
He has embraced training and all the hard work and has really got off on it. It has inspired him and it has obviously paid off.
Murray has been brilliant during the whole week.
John McEnroe gave him a B grade for his efforts so far but I'd give him an A.
Stanislas Wawrinka is next up in the fourth round. He is a good volleyer and his single-handed backhand is amazing. But there's no doubt Murray will be ready for the second week.
He will probably be spending Sunday like any other off day. He'll be heading to the practice courts, hitting some balls, stretching, having a massage and just staying sharp.
He'll be pretty loose though because his third-round match wasn't much of a challenge.
Can he make the final? I reckon he'll be there up against Federer.
He was a little shaky in his first-round tie with Robert Kendrick and understandably had a few nerves.
But he loosened up against Ernests Gulbis in the next and against Troicki was just exhibition stuff - some of his touches were simply amazing.
He is looking sensational. But Federer also looks great - he's calm and very relaxed.
As Murray approaches the second week, my advice would be 'don't read the newspapers'.
But he seems to like having a read and listening to what the media are saying! Hopefully he'll stop doing that...
