Ruben Vargas is reportedly the subject of advanced talks between Villarreal and Sevilla, who are negotiating terms ahead of a possible transfer. The midfielder has long been on the radar of Villarreal, who see him as the perfect addition to their squad as they look to strengthen a key area of the pitch. Progress on talks has been made, though a final agreement is not yet in place and other clubs are said to be weighing-up whether to join the race for his signature. Villarreal have laid out their intentions, but valuation and timing remain under debate. Aston Villa, Crystal Palace and Tottenham are keeping tabs in case talks collapse or progress slows further. So far this season, Villarreal are steady at both ends (1.75 goals scored per game, 1.0 goals conceded per game). The role for Ruben Vargas would be to keep that balance while lifting performances across the pitch. Sevilla have also been linked with Mohammadjavad Hosseinnezhad while Villarreal are reportedly monitoring Arnau Tenas, Artem Dovbyk and Tanitoluwa Oluwatimikhin Oluwaseyi.
