Glasgow Rangers boss Mark Warburton has already done plenty of business during the window, but Thompson expects more to arrive at Ibrox.
Steven Thompson has predicted that Rangers will strengthen their options up front before the start of the season, but also insisted that he expects Kenny Miller to still be influential for the side, the Evening Times reports.
Mark Warburton has significantly bolstered the Gers' midfield options during the early stages of the transfer window, with the likes of Joey Barton, Josh Windass and Jordan Rossiter all joining ahead of their Scottish Premiership return.
But former Gers forward Thompson has claimed that Warburton needs to now focus on adding depth in the striker department.
"I'd still expect to see another striker arrive as you need to have competition for places. You would want to be carrying more than two out-and-out strikers in your squad," he told the Evening Times.
While the 37-year-old believes that the Light Blues need extra options up front, he is confident that Kenny Miller has shown enough during their successful Scottish Championship campaign to suggest that he can still handle the demands of the top flight.
"A lot of folk will question if he can step up again. Obviously it's a step up from the Championship to the Premiership but to me, Kenny looked as sharp as ever last season," he added.
"He got 21 goals and will continue to score goals. It will be harder for him and he may be used more sparingly. But in my opinion there is no doubt Kenny will be influential for Rangers again next year."
With Martyn Waghorn enjoying an excellent first year at Ibrox, and Ryan Hardie and Michael O'Halloran hinting that they can make a contribution at the highest level, finding another forward may be slightly lower down on Warburton's list of priorities given their lack of depth in defence.
However, it may be the addition of another goalscorer that sees the side elevate themselves towards the title picture in the top flight.
