Laura Robson insists she will need to spend more time on the practice courts with new coach Miles Maclagan if she hopes to make an impact at Wimbledon.
The British No 1 suffered a miserable start to her grass-court campaign at the AEGON Classic in Birmingham on Wednesday, losing in straight sets to Daniela Hantuchova.
She was playing her first competitive match since teaming up Maclagan, but went down to a disappointing 6-3 6-4 on the new Ann Jones Centre Court.
Robson admits there have been 'no miracles yet' although she is excited at the prospect of working with the 38-year-old who coached Andy Murray to his first grand slam final at the US Open in 2008.
"It's good so far and we've only had less than a week together so there's no miracles yet, but in general my serve is looking a bit better than it was and I'm feeling pretty good on court," said the world No 37.
"There's no magic solution, it takes time and a lot of hard work on the practice court to fix anything and over the last couple of days we've done a lot (of work) on my serve which I think looks a bit better, so I think we have a lot to work on."
In 2009, Robson came agonisingly close to beating Hantuchova as a 15-year-old on her full Wimbledon debut.
However, that day she produced two consecutive double-faults on match point to hand her opponent a route back into the match before going down in the decider.
At Edgbaston, Robson won seven of 26 points on her second serve, although she committed just four double faults, which is something she is happy to take away as a positive.
"For (Roger) Federer it's not great, but for me it's phenomenal," she joked. "Seeing as I was averaging about 15 double faults a match, it's a big improvement and it can always get better."
Although Robson was downbeat about her performance against the experienced Slovakian, she is looking forward to playing at Eastbourne next week as her preparations for Wimbledon continue.
"It's always tough to play your first match on grass and I haven't had a huge amount of practise on it," she said.
"I think I can play better but I've played worse matches as well. I need to try and get as much time on the practice courts as possible."
And with the second grand slam of the year just a fortnight away, Robson says there isn't any reason why she can't do well at SW19.
"I've got to stay positive, confident and focused on Wimbledon. I don't see why I can't do well there - I've always played pretty well in the past."
Robson will hope to avoid Hantuchova though after the 30-year-old, who has dropped down to world No 60 after suffering a stress fracture in her foot last year, made an impressive return to WTA action.
She has now beaten Robson in their last three meetings and the young British hope wasn't at all surprised by her performance.
"Daniela's favourite surface is grass and she plays very flat, so there was never ever going to be a huge amount of rallies. I thought she served well and returned pretty well but I'm looking forward to Eastbourne."
