Belgian tennis star Kim Clijsters will make her comeback to the WTA Tour wearing Fila apparel and footwear after the completion of a kit sponsorship deal with the Italian company.

Former world number one Clijsters, 26, is making her return after two years out of professional tennis, during which she got married and had a child.

Fila said the sponsorship deal was part of the company's "ongoing commitment to tennis as a core category".

"She is a proven champion whose drive, athleticism and style are consistent with Fila's core values," Fila chairman Gene Yoon said of Clijsters.

"Kim is a fan favourite in the tennis community and we are pleased that she will continue to wear Fila's performance tennis line as she returns to professional tennis."
