I respect Murray's contribution to tennis, I was so happy when he got to number 1 even though I criticise the way he plays, if there was a time where Murray should just hit hard, let rip from the forehand side now is the time, try to finish more points off via the net. Hit a harder second serve.
Matteo would be shocked if Murray dictates play rather than let his opponent dictate the play, you have to take the racket away from Berrettini in order to beat him.
I'm not fond of "but he has had a career changing hip operation" as an aside, when you step out on court you're fit to play, there are no excuses, we've been through this when Nadal played injured, when he stepped out on court he's 100% in regardless of issues. Sometimes you have to put sentiments in the draw and focus on the one thing we all played tennis for either professionally or amateurly, to win.
