Messi was then sent off in the dying minutes of additional time when VAR recognized an off-the-ball event Villalibre, as the Argentinian fiercely smacked the Athletic player to the ground.

The Catalans are sitting third in the Primera Division, however, seven points back of leaders Atletico Madrid having played two games more.
Although on Sunday saw Messi first red card in a Barca shirt, it’s not the first red card of the attacker’s career.
He has been sent off for Argentina on two events, including largely on his international debut, which lasted just a minute when he came on as a substitute.
