Manchester City have tried to add radical physiotherapist Mariana Kovacevic to their medical staff.
Arsenal striker Robin van Persie has turned to Kovacevic to speed up his return from an ankle ligament injury.
The Daily Mail says City trio Pablo Zabaleta, Vincent Kompany and Nigel de Jong have all taken their search for a remedy to her Belgrade home.
City even flew Kovacevic over to Manchester earlier this month and discussed the possibility of adding her to their medical staff.
Wary of publicity and secretive about her methods, she declined their invitation but made it clear she would continue to accept players as patients.
