Emmanuel Adebayor believes William Gallas was right to publicly question his Arsenal team-mates' stomach for a fight.
Gallas was stripped of the club captaincy in November after criticising his team-mates for lacking bravery, while he also revealed the rifts in Arsenal's dressing room that have threatened to derail the Gunners' season.
Adebayor, who labels Gallas as his 'big brother', feels the defender's outburst may have been just the thing Arsenal needed and told Aujourd'hui Sport: "There is some truth in what he said. Someone had to say these things, to make each person face up to their responsibilities. If he had said nothing, where would we be today?"
He added: "Gallas has always been like that - he has experience, he has won titles, played in a World Cup final.
"He doesn't throw these thoughts around lightly. He said something because it was necessary to do it.
"He is indispensable to the team. He is Arsenal's rock - his behaviour since the armband was taken off him proves that."
