Middlesbrough's belief in avoiding Premier League relegation has been bolstered by after Wednesday's 1-0 Tees-Wear derby win against Sunderland, says defender Ben Gibson.
Boro are second from bottom with four matches left to play, and are six points behind 17th-placed Hull.
Three of Boro's four remaining games are against current top-four teams.
"We've got that one over the line," Gibson told BBC Tees. "Why can't we beat Manchester City this weekend?"
Middlesbrough ended a 16-match winless run in the league with the success at the Riverside Stadium.
"We got that win, we're confident, even if people think we're down or won't win, whatever.
