Willian laced up in a pair of the Puma Ultra soccer cleats instead of his usual choice, the Nike Mercurial Vapor.
The fact that he wore Puma's Ultra boots is a clear indicator that he will leave Nike for Puma.
Willian was already rumored to leave Nike in 2018
However, it is not the first time that Willian is rumored to leave Nike, In January 2018, it appeared like that the boot contract of Chelsea FC and Brazil superstar Willian has ended with December 31 2017 - the Brazil midfielder blacked-out his Nike Mercurial Vapor XI cleats from the 'Fire & Ice' collection back then. However, Willian reverted to branded Mercurial boots in 2018, ditching those rumors.
A Puma deal appears most likely
There has been never official news on Willian's contract situation, so we can only guess what happened since 2018. It appears most likely that he extended his Nike deal in 2018 (maybe for less money than he originally wanted) and that he could be without a contract again soon (from 2021?). So he and his agent are looking for possible new partners, with Puma seeming to be the favorites.
Watch out for Willian's boots in the coming weeks.
