Rangers have brought in as many as eight new players this summer.
The Gers used the loan market well last season as they won promotion back to the Scottish Premiership, bringing in the likes of talented youngsters Dominic Ball, Gedion Zelalem and Nathan Oduwa.
This summer, in contrast, Warburton has instead opted to make permanent signings, a strong suggestion that he will not be looking for any favours from south of the border via the loan market.
It’s an interesting strategy considering his contacts in England, but Johnstone feels it’s the right one as Rangers now look to build a squad for the long haul, capable of challenging for titles.
“I can understand fully though why he has changed tact this year. Now Rangers are in the big league they will be looking to build a side that can compete at the top end of that table,” Johnstone told the Evening Times.
“He has a lot of good young players already, and now he has brought in some really experienced heads to help them along, which will be needed in the Premiership.
“I’d be very surprised if any loan signings come in at all, because Mark Warburton I’m sure will be looking to now build a Rangers team for the future.”
Warburton now has a big squad at his disposal at Rangers, and the former Brentford boss may feel his side’s younger players will now benefit from having plenty of experience around them.
The side which won promotion last term was one of the youngest on average in the club’s history, and few could argue the need to bring in the likes of Joey Barton and Niko Kranjcar to restore some balance.
