Glasgow Rangers' recent form has increased the pressure on Giovanni van Bronckhorst, especially with the Ibrox side nine points behind the current league leaders in the race for the Premiership title.

Truth be told, only one of the Dutchman’s seven summer signings has suitably impressed. Striker Antonio Colak has scored 14 goals in all competitions, however, the burden shouldn’t fall on just one player to be the focal point of the team.

Alfredo Morelos has been in woeful form this campaign, netting just three times. His contract is due to expire at the end of the season and the majority of the Ibrox faithful are now bracing themselves for him to either be sold or leave for free in the summer.

As such, with the January window fast approaching, Van Bronckhorst should be revisiting a move for Sunderland striker Ross Stewart.

The Scot was linked with the Light Blues back in the summer as a replacement for Morelos, however, nothing ever materialised. His contract is also set to expire at the end of the season and this should prompt Van Bronckhorst to revisit a potential move.

Although Gers usually play with just one up front, a duo of Colak and Stewart could be an excellent option ahead of the second half of the season.

The Sunderland hitman has scored 78 goals in his career to date and, despite not being an out-and-out centre forward like Colak, he would be a perfect foil for the Croatian, allowing him to benefit from his hard work and boundless energy.

A change in formation might do the Glasgow side the world of good, and two centre-forwards could certainly cause a host of problems for opposing defences, especially with a duo in the calibre of Stewart and Colak.

Having scored 24 goals in League One last season, with Sunderland gaining promotion through the playoffs, journalist James Copley hailed the player as “unbelievable” during his stunning season.

He might not be the big-name signing the supporters expect, but if the club can secure him either for free at the end of the season, or for a reduced fee in January, it might be shrewd business indeed.
