Heather Watson’s new coach is Diego Veronelli.
The British number three appointed the Argentine after several months without a coach, after splitting with Columbian Mauricio Hadad in July.
Britain’s Jeremy Bates worked alongside Watson for her US clay court games in the summer, after a year in which the Guernsey-born player was hampered by illness, as she battled with glandular fever.
Veronelli is the second Argentine coach to feature in tennis news recently, as his compatriot Dante Bottini was recently appointed to work with Japanese world number 16 men’s singles player Kei Nishikori.
Veronelli, who has coached Brazilian Joao Souza and Argentinian Paula Ormaechea, is based in Florida, but has been working in London with Watson recently.
They will travel to Australia on 30 December where Watson, who has slipped in the world rankings, will hope to qualify to play in Brisbane and Sydney before the Australian Open.
Her career peak was at 39 in the world in early 2013, but a series of disappointing early round defeats saw her drop to her current place outside the top 100.
She was recently quoted as saying that snooker’s Ronnie O Sullivan was an early role model but added, "Whoever is your hero is your hero.
"It doesn't matter if they're male or female, it doesn't matter what sport they play - it's whoever inspires you.
"It doesn't even have to be an athlete or a famous person, it can be somebody within your family, your tennis coach or your teacher at school."
Now she says she’s looking ahead to 2014.
"Glandular fever was an obstacle but it's gone," Watson told BBC Sport.
"It happens, people have setbacks. I'm definitely looking forward to putting it behind me and starting fresh in the new year.
"It never crossed my mind that I wanted to quit tennis, I just love it too much and it's such a huge part of my life, so that could never happen."
