Loan signing Haris Vuckic believes Rangers can catch Hearts in the Scottish Championship title race.
The Ibrox side trail the leaders by 16 points but have two games in hand. The eventual league winners will gain automatic promotion to the top flight.
"It's a big gap between first and second," said Vuckic, who is one of five Newcastle players joining Rangers on loan for the rest of the season.
"But I think, realistically, we can catch them up."
Vuckic spoke with Newcastle boss John Carver before deciding to move north and the Slovenian midfielder, 22, said: "I wasn't in his plans at the moment and he advised me to go and play football.
"I want to score goals. I am a creative player, I like to create the chances."
England Under-20 midfielder Gael Bigirimana, Northern Ireland international Shane Ferguson, Swiss Kevin Mbabu and fellow defender Remie Streete are the other St James' Park players spending the rest of the campaign with Rangers.
Englishman Streete, 20, has played for Newcastle's under-21 side this season and also featured three times during a loan spell at Port Vale earlier this term, meaning he has already been registered with two clubs in the current campaign.
And he explained: "It's all signed from my end.
"I think the different federations in different countries have different rules. I've been told from my agent that the Scottish FA have allowed us to make the transfer so hopefully it should be fine.
"The one thing I was missing at Newcastle was first-team football every week. We've come here to obviously help the team get promoted, get first-team games under the belt and help everyone in the long run.
"I'm quite comfortable on the ball. I'm quick, I'm strong so I hope I've got a lot to offer."
Bigirimana, 21, had never been to Scotland before making the move to Rangers and explained: "I'm a centre-mid. I'm at my strongest when I've got the ball at my feet.
"I'm a player who will always want the ball. I'm a fit lad. I can run, I can tackle."
