Benfica lodged the complaint after Valverde swung his arm towards Samuel Dahl's head in the 80th minute of Tuesday's Champions League Round of 32 match. While the level of contact was unclear and VAR didn't intervene, Portuguese club officials have still taken action.
The two teams meet again next Wednesday with Real Madrid holding a 1-0 aggregate lead. With Vinicius, Prestianni, Valverde, and Dahl all expected to feature, the return leg at Santiago Bernabeu could be heated. UEFA is currently investigating both the Valverde-Dahl incident and the Vinicius-Prestianni case, though no suspensions are anticipated.
