Rangers striker Alfredo Morelos has committed his future to the club by signing a one-year contract extension.
The 21-year-old Colombian joined the club on a three-year contract last summer from HJK Helsinki and has made a fine impression so far, scoring 17 goals in all competitions.
He was linked with a move to China in January but stayed with Rangers and has now given them a further boost ahead of Sunday's Old Firm game, which is live on Sky Sports, by signing a new contract.
Morelos said: "I am very happy to have signed a new contract with Rangers.
"I know how important the club is in Scotland, how many titles that it has won, and how much history that it has.
"I am really happy here and I am working hard for the team.
"I love it when the fans show their support to me and sing to me. I'm really grateful for their support and want to repay them with performances on the pitch."
Rangers boss Graeme Murty said: "We are delighted that Alfredo has committed his future to the club today.
"He is a very talented player and one that we know we can work with, to make even better.
"He has a massive opportunity at this club and we feel that he can continue to improve and even realise his international ambitions here at Rangers - and help the club to challenge for silverware."
Rangers vs Celtic

Graeme Murty believes victory over Hearts on Saturday would demonstrate the progress Rangers are making amid talk of a title challenge.
The Ibrox club are nine points behind Celtic, who have won the last six Scottish Premiership titles, ahead of the weekend's action which sees the top six all in action against each other.
Murty, who saw his side power to a 5-3 victory on the road against Hamilton last weekend, could cut the gap to their Glasgow rivals to six points ahead of the Hoops' visit to Aberdeen on Sunday, live on Sky Sports Football.
Asked whether he had given up hope of mounting a challenge for the league title, Murty said: "I think if we win tomorrow [Saturday], we will say we are in a better position than when we walked in, and we are moving closer to where we want to be.
"We will finish where we deserve to finish at the end of the season, we will be the team we want to be or closer to where we want to be by the end of the season.
"This team is still coming together, we are still in a position that we are improving all the time. If we can carry on getting positive results who knows what might happen.
"I have said to the players to aim high, don't worry about anything else, just aim high, be as competitive as we can and have a positive end to the season."
Murty's first game of his second spell of caretaker charge of Rangers was a trip to Tynecastle in October and Pedro Caixinha's replacement believes he is making his mark on the squad and allowing them to express their ability on the pitch.
When asked about his personal development as a manager over the past few months, he said: "I would like to say I am calmer, but that is just on the outside.
