Fabio says Boro will continue to fight for Premier League survival until the very end following Wednesday's win over Sunderland at the Riverside.
The team face a quick turnaround of games this week, with Manchester City heading to Teesside this Sunday.
And Fabio is counting on the squad's fighting spirit to carry them through the remaining four games in the league.
"We're a strong group of players and we have to believe that we can get out of it," he said.
"We know it's going to be a very hard job to do but you have to believe. We've got some difficult fixtures but we have to go to the pitch trying to win every single game.
"I'm 26-years-old now and I've had some great experience in the game so I hope that will help me in the upcoming games.
"We've never lost fight in that dressing room and everyone is going to fight until the end."
