The Inter coach has struggled to match the deeds of predecessor Jose Mourinho so far this season.
Asked to give his first six months at Inter a score out of 10, Benitez said: “6.75. The team can still improve. There are many injured players and when we are all ready you will see an even better team.
“I am happy with the effort that the team has made in the last two games. I am very proud of my players in this period.
“The participation in the Club World Cup was earned by the players who are still here, by the club and not just by the Coach. I must only think that we can win.
“I have confidence that we can win other trophies, even the Scudetto.
“At the beginning of the season when everyone was available we played good football. Many of the players who did well last year are now unavailable from Julio Cesar to Maicon, from Diego Milito to Thiago Motta who has come back.”
