Central defender Danny Collins has hailed Sunderland's 'togetherness' ahead of their vital Premier League relegation run-in.A sequence of seven games without a win has seen the Black Cats sucked back into the fight for survival.Ricky Sbragia's side are just two points above the drop zone with six games of the season remaining.Collins, though, is feeling confident and is hopeful of a vital result at home to fellow strugglers Hull City this weekend.He said in The Northern Echo: "I've been in this situation before and sometimes one or two go missing or get a bit tense in difficult circumstances."That isn't going to happen here - we're all pulling in the right direction and we are all behind the gaffer. The lads have that togetherness."Collins added: "We obviously know how big the games are. Hull and West Brom are down there fighting - a win can take us above them and change things completely."We know how important those games are - a win could lift us massively. You look where the points are going to come from and these are the kind of games that you target."They're (Hull) just coming off the back of a 3-1 defeat up at Middlesbrough, so hopefully confidence is a little bit low. We can put the pressure back onto them if we start well."
