The midfielder has reflected on the team's performance on Tuesday, and has backed the coach to boost the player's confidence and get the best out of the squad
The Brazil-born Italy international believes that Ranieri's decision to mix up the team will benefit the players after the coach started the match by pairing Diego Milito and Giampaolo Pazzini up front, while Diego Forlan was introduced late in the game from the bench. Marco Faraoni also started the contest, as did Sampdoria's on-loan debutant Andrea Poli.
"[Claudio] Ranieri is experienced and he's seen lots of things in football. He knows how to manage us players," Motta said.
"At the moment, we have to think about what's good for the group, so I think it's right that we should alternate and each of us take it in turns to play or rest. If we rotate like this we'll do better."
A second-half goal from Japanese left-back Yuto Nagatomo clinched the result for the Inter, who are now up to seventh in the Serie A table, 10 points behind joint-leaders Juventus and Udinese, and Motta is adamant that the squad are rediscovering their self-belief.
"Certainly before the goal we were playing against a very cautious team, who did well defensively while trying to score," Motta said.
"After we went 1-0 up the game opened up more and it was better. Genoa changed a lot but we're used to thinking about ourselves regardless of who we're playing. It was important to get some continuity going - that was important for the team's morale."
Inter's next Serie A fixture takes place on December 18 at Cesena.
