Air of unknown in Rangers' recruitment - Allan

Rangers' new signings may have to "hit the ground running" if there is to be any prospect of a title race, says former Celtic midfielder Scott Allan.

The Ibrox side have welcomed five new bodies into the building so far this summer, as well as the addition of Mohamed Diomande on a permanent basis and the loan return for Oscar Cortes.

With Philippe Clement stressing on several occasions the need for a rebuild, Allan suggests recruitment could be the definitive factor in the destination of the title.

"Rangers have made some signings, ones that we don't really know what to expect from," he told BBC Radio Scotland.

"That's the biggest problem with Rangers signings and Celtic signings - it's who hits the ground running.

"Kyogo came in and did that. Some guys do take time to bed into these clubs because there is that pressure. It's not easy.

"The ones who get the signings right build up momentum. It's going to be interesting with the Rangers/Celtic game so early in the season. All eyes will be on that.

"Rangers have a hard game first game of the season. Rangers are trying to get their business done early, Celtic are a little bit slower."
