Ally McCoist admitted it was "far from ideal" that he won't be able to field a number of his new signings, including his most recent, Bilel Mohsni, as trialists in the opening games of the season.

Only those players whose international transfer certificate was last held with a Scottish club will be eligible for Rangers' matches in SPFL League One, the Ramsdens Cup and the League Cup before the end of the club's year-long registration embargo on September 1.

That means Arnold Pernalta, Stevie Smith, Richard Foster and Mohsni, who agreed a two-year deal yesterday could, potentially, sit out as many as eight games before being allowed to make their competitive debuts.

There are also restrictions affecting the four players – Nicky Law, Nicky Clark, Cammy Bell and Jon Daly – signed from Scottish clubs. A maximum of two trialists can play in tomorrow's Ramsdens Cup first round tie against Albion Rovers, but then McCoist can field none in the second round should Rangers progress. No trialists can feature in Rangers' League Cup first round tie away to Forfar Athletic on August 3, while two can play in each of the four league games although each individual can only feature a maximum of three times.

"Nothing comes as a shock but it is a major disappointment," said the Rangers manager. "The one that completely baffles me is how you can play a trialist in the first round of the Ramsdens but can't in the next round? It's strange, that's all I'm saying.

"Pre-season has gone well and you have a squad you want to build on but you can't really do it.

"It creates a false start to the season but it is a problem we'll have to handle. There's a positive way to look at it – the boys who start will be trying to keep the jersey and perform at a level that will make it extremely difficult for the other boys to get in."
