Rangers have already made eight signings this summer, as Warburton looks to bolster his squad for the new campaign.

Rangers earned promotion with a thin squad, but Warburton has quickly tried to add depth for the new campaign.
Rangers have been the busiest side in Scottish football so far this summer.
And Warburton said: “A lot of our business has been done early which we wanted to do as a club, so it’s good news and it puts a good message out to the fans.”
