British women's No 1 Laura Robson admits she will be working on improving her consistency as she continues to work with new coach Miles Maclagan.
The 19-year-old began training with Andy Murray's former mentor last week after splitting from Croatian Zeljko Krajan.
Robson, who has beaten the likes of Petra Kvitova and Agnieszka Radwanska this year, knows where she needs to improve her game.
Speaking to BBC 5 Live's Sportsweek programme, she said: "They just have a lot more experience and if you come out firing in the first set they generally have back up.
"They always give themselves the best chance to win. I think consistency is probably the biggest difference in terms of switching from juniors to seniors and from lower-ranked to higher-ranked.
"My year so far has been pretty up and down and I've had good wins but also some bad losses.
"So I'm just trying to focus on being a bit more consistent in the next weeks, and I'm really looking forward to getting into the grass season."
Robson, ranked 37th in the world, revealed Murray had played no part in introducing her to Maclagan, a former British Davis Cup player who has also worked with Cypriot Marcos Baghdatis and Germany's Philipp Kohlschreiber.
"I didn't speak to Andy," she said. "I just thought it would be a good thing to have for the next couple of weeks and I really respect Miles' opinions and I think he's always been a very good tactical coach. So we'll see how it goes."
