Rangers moved within two games of ending a three-year exile from the Scottish Premiership after holding off Hibernian in their play-off semi-final at Easter Road.

Former Rangers midfielder Gennaro Gattuso says he would be interested in taking the manager role at the club, but the matter is complicated.
The Scottish side are without a manager following Ally McCoist being put on gardening leave and caretaker Kenny McDowell resigning.
Gattuso, who was back in Glasgow for Fernando Ricksen's charity match, is willing to step into the breach, but feels it would be too complex to do so.
"I still have a lot of memories here. It was 15 years ago that I started to play here. I felt the same running out there again. I'm maybe carrying five of six kilos more but it still felt fantastic.
"But now the club has big problems. They need to find a way of solving those.
"Of course I would be interested in the vacancy. I stopped playing two years ago. Now my job is to become a coach. That's normal.
"But at this time the road [to the Rangers job] is far away."
