No, it's someone already looking for a new club for a while.
Sylla seems to be unhappy to cut her salary, that's why she didn't renew yet. There were strong rumors about 2 middle-level teams from Russia offering a contract to her, but she didn't want to go there. Lately it seems Dinamo-Kazan wants her to replace Bethania de la Cruz. I won't be surprised if she stays in Conegliano after all. Russian Superliga is quite unattractive on the women's side, which is quite funny considering their men's league is kinda amazing (close to Superlega and its level).
