Argentina captain Lionel Messi does not possess the same leadership quality as Portugal skipper Cristiano Ronaldo, according to a former FC Barcelona player.
Messi has come in for a lot of criticism following Argentina's winless start to the 2018 World Cup in Russia.
Ronaldo has already netted four goals in the tournament and are on the brink qualifying for the knockout stage.
Former Barca midfielder Emmanuel Petit, who won the World Cup with France, wants to see a better mentality from Messi.
"He's not a leader. He's no Ronaldo in that regard. Messi is one of the best players ever, but he needs to show that mentality," Petit told bookmaker Paddy Power.
"He needs to wake up! When things go well with Barcelona he's a terrific player.
"We've seen it in the Champions League though, when things don't go well, he can disappear on the pitch.
"He's not there anymore. He's not running, he's walking. He's not concerned about the ball. Come on."
