Tensions between the benches of Barcelona and Atletico Madrid boiled over during Tuesday's Copa tie.

The match finished 1-1, with Barca advancing to the Copa del Rey final on aggregate.

Quatro cameras covered both dugouts and picked up several confrontations between Atletico coaches Diego Simeone and Mono Burgos and Barca's Luis Enrique and Juan Carlos Unzue.

At one stage, Simeone accused Enrique of shoving the fourth official. Simeone also traded insults several times with Unzue.

There's also suggestions Barca fullback Aleix Vidal, in a wind-up for Simeone, made a gesture of cutting his sleeves.
