4. Divock Origi
Divock Origi had a breakout tournament at the 2014 World Cup, impressing on the highest international stage and earning himself an almost immediate transfer to Liverpool. After spending his first season on loan to Lille, Origi returned to Anfield, scoring 21 goals in 76 appearances over two seasons.
The Belgian then lost his place in the starting line up, and spent the 2017/18 season on loan with Wolfsburg, scoring six league goals in 31 games. Yet no matter how well the striker performed in Germany, there would be exactly no chance of him taking Mané, Firmino, or Salah's place in the Liverpool front three.
Four years after he caught Liverpool's eye at the World Cup, Origi has been left out of Belgium's 2018 squad, and without first team football he is unlikely to earn any more caps for his country. This is where a move to Rangers would help.
Last season The Gers scored more goals than any other team in the SPL, and should Origi join the ranks he will get the opportunity to score more than his fair share, helping Gerrard and co. send a message to the rest of the league that they mean business.
