La Liga has announced an agreement with Sockatyes to promote the videogame Pro Evolution Soccer 2015 on socks worn by its players.
The game's logo will appear on an elastic strip that supports the upper part of the sock.
"The fact a global brand such as Konami has decided to use the method until the end of the season shows that we have taken the correct decision partnering with Sockatyes," La Liga's general director of marketing and sales Adolfo Bara Negro said.
It is the first time that such advertising has been used in professional football.
