“With any great player, I think it’s a mix of incredible talent, mental strength, single-minded focus, determination and a lot of hard work,” explained Murray.
“They’ve all got good teams around them too which really helps. I also think that because tennis is such a mental game, the experience they have is a big factor now too.
“They are able to draw on that against the younger players, and [thus] still dominate the game.”
He added “”When you’re coming up against someone who’s won 17 of them [Grand Slam titles], or 19 or 20 of them, which these guys are doing now, it’s pretty intimidating,” said Murray.
