It has been a very busy summer on the transfer front for Rangers as Jordan Rossiter, Joey Barton and Clint Hill have followed Matt Crooks and Josh Windass - the duo who signed pre-contract agreements in January - in joining the Ibrox club.
Niko Kranjcar is heavily expected to be the sixth new face arriving at Rangers this summer as he reportedly undergoes a medical with the Gers, according to BBC, while The Express have reported that Crystal Palace defender Adrian Mariappa has been offered a contract.
There has, however, been less substantial rumours doing the rounds, with Uganda midfielder Khalid Aucho - who plays for Kenyan outfit Gor Mahia - strongly linked with a switch to Warburton's side, before it was revealed that he was heading to Aberdeen, say Supersport.
“You see these stories and they are quite bizarre. I’ve been linked with players I’ve never heard of," he told The Telegraph.
"Apparently there have been players turning us down who I have never heard of, but if the fans want to believe that I can’t control it."
The great thing from a Rangers perspective is that they have signed these players for free, with the exception of compensation and signing-on fees.
