Style of play
Upon signing for Arsenal in 2018, The Independent's Jack Austin stated "Torreira is exactly the kind of no-nonsense midfielder the club have been craving", adding that in Uruguay colours during the 2018 World Cup "he went about his job as the deep-lying pivot in the middle of the park with none of the fuss and all of the discipline of a player who has built a tidy reputation for himself in Serie A", while assessing his chief weaknesses as a lack of height in aerial duels and little goal threat. WhoScored notes that he is a player that likes to shoot from distance and often gets fouled. They also note that he likes to play short passes and make tackles.
