The Gunners-linked midfielder squared up to Carlos Zambrano in Chile’s 2-1 win over Peru.
However, the combative star was also embroiled in an ugly incident in the first-half of the clash, where he squared up to Peruvian defender Carlos Zambrano.
Zambrano se merecía su amarilla, pero Vidal fijo una roja por esto. ¿El arbitro está comprado o ciego? pic.twitter.com/YUP1juCAQj— ✨ (@daniamacedo) June 30, 2015
Vidal pushed the Eintracht Frankfurt centre-half in the face and was lucky to escape without punishment.
Zambrano was not as lucky, with the Peru man being sent off later in the half for a high challenge on Charles Aranguiz.
If Arsenal are to land Vidal, there is no doubt that the Chilean star will bring aggression and combativeness to a team that has been accused at times of lacking physicality.
However, the former Bayer Leverkusen star could also be a disciplinary worry, which Arsene Wenger will be keen to avoid after having players at the club in the past that have been sent off too many times.
