“I don’t have a clue what will happen in the summer. Obviously the move only happened a couple of days ago so I’m just concentrating on doing my best for Rangers.”Saturday’s 1-0 win moves the Ibrox club eight points clear of second-placed Hibernian, although the Edinburgh men have played a game less. King was a Championship title winner with Hearts last term and believes he can now help his new team repeat the feat this season. “To score the winner in the 89th minute, there is no better feeling,” said the Scotland Under-21 international. “It was a rare header for me – that’s probably the weakest part of my game. I’d only scored one goal with my head before and it was against Falkirk last season.“It’s a massive three points because it was a stuffy game and over the course of the season you are not going to play your best in every game. But the most important thing is to win. That’s what we did today. “I came in and trained for about 45 minutes. I’m still getting to know the boys here and to learn the philosophy. It was difficult because Hearts play a different style. “It will take me a few weeks to get into the swing of things and to know how the gaffer wants me to play. I won the title with Hearts but I play for Rangers now and want to help them win it this time.” He said: “I’ve only started seven league games this season for Hearts, that’s compared to last season when I started loads of games. “So I felt like I needed to get out because it was stalling my development. That’s when Rangers came along.“It all got sorted out in a day. I’m just glad to be here. I came on and got the winner so I’ve got off to a good start. “Hopefully I can keep playing and see what happens. The gaffer at Hearts gave me his best wishes when I left and told me he thought Rangers would be a good loan move for me. I’ve not really spoken to him since I’ve left though. Billy King explained why he was so keen on a move to Rangers, amid fears that his career was stalling at Hearts.The attacker joined Mark Warburton’s side on a loan until the end of the season earlier this week, and scored Rangers’ winner against Falkirk on his debut.Hearts say they expect to see the 21-year-old winger back in Edinburgh when the season closes but both the player and Rangers boss Mark Warburton have refused to rule out a permanent signing if he continues making the kind of impact he produced against the Bairns. For the meantime, though, King is just glad to be looking at a chance of regular first-team action after a frustrating season under Jambos boss Robbie Neilson.
