"Make-or-break time, squeaky bum time, the business end - there are many clichÃ©s to describe the final stages of the season," Gordon said ahead of Hull's visit to the Stadium of Light on Saturday.

There are probably eight teams in it and it's going to be tense till the end.
"Two of those eight are Sunderland and Hull - and a win for us on Saturday would go a long way towards us staying in the Premier League. The quicker we can get the points we need to stay up the better."
Sunderland have slid to fourth-bottom of the league after losing their last four games and Gordon knows his team must get back to winning ways against six-bottom Hull before attention if turned to a trip to West Bromwich Albion.
He is heartened by the spirited display in last Saturday's 2-1 defeat by Premier League leaders Manchester United.
"It's a big game and if we can recreate the same kind of performance and atmosphere as against Manchester United last weekend, I'm sure we can get the win," the former Hearts skipper said.
"We know the situation we are in and we know what we have to do. Yes, we' ve been on a bad run but we know that over the next two games we have a good chance of doing something about it. Six points is the target." The 26-year-old continued: "We did okay against United but that has gone.
"Hull will be a completely different test and we need to be up for it, we need to make sure it's not a flat performance like against Wigan last month.
"We nearly snatched a point from the United game when no one expected us to and we can take encouragement from that performance but now it's all about points not performances.
"We've worked hard this week and we'll be up and ready for the Hull game, as I'm sure the fans will be."
