RANGERS will have to wait for Uefa's verdict on the violent scenes which scarred their defeat in Pamplona.

The Ibrox club have written to Uefa complaining about the lack of segregation inside Osasuna's Estadio Reyno de Navarra and the heavy-handed tactics of local police.

They are also meeting the Rangers Supporters' Assembly to compile a list of eye-witness accounts from fans.

Uefa will hold an investigation when all reports are received, but that may not even be next week.

They have the report from match delegate Manos Mavrokoukoulakis, of Greece. But more important are the findings of German police chief Ulrich Grzella, who was specially appointed for the match because of security fears.

A Uefa spokesman said today: "The report from the delegate has arrived, but it is more from the security officer's report that decisions will be taken. Security officers are appointed for certain matches, particularly when large numbers of fans travel to support the away side.

"Mr Grzella will have to include detail from relevant parties and we do not expect that to arrive until Monday.

"Our disciplinary unit will then gather the reports, plus submissions from both Osasuna and Rangers, before deciding what action is necessary. There is a scheduled meeting of the Control and Disciplinary Body next Thursday, but it may be too soon to be on the agenda.

"There is no urgency in dealing with this because Rangers have been eliminated from the tournament."

Rangers voiced their concerns to both Grzella and Mavrokoukoulakis that Osasuna's assurances regarding segregation were not realised.

They will urge Uefa to introduce a common set of standards by which all visiting supporters across Europe must be treated.

The British ambassador is contacting Spanish Government representatives in Pamplona to ask for an explanation of the security failures.

However, Navarra police spokesman Antonio Ferreiro has defended his officers, and says he has footage from 53 CCTV cameras to back up his claims.

He said: "Rangers supporters threw coins and lighters at Osasuna fans and even spat on them. Some Rangers fans were heavily under the effect of alcohol. During the day, some drank incredible amounts of alcohol. Some fans were doing the toilet in the ground.

"Police immediately intervened when informed about it. Police are allowed to act in any way to stop fans causing trouble.

"The problem was clearly because there were more Rangers fans inside than the legal number arranged. That is why the segregation problem started. Rangers fans were in areas where they shouldn't have been.

"It is unfair to say that, generally, Rangers fans behaved badly. Only a few misbehaved and let down the perfect conduct of the rest."

There were only two arrests, one before the match and one after, both for drunkenness.

Martin Bain, the Rangers chief executive, and security chief Laurence MacIntyre are meeting Rangers fans to record their accounts.

They are concerned that banned hooligans, with flags bearing the name of hooligan group Inter City Firm, were among the away fans.

MacIntyre said: "There were people in the crowd who should not have been there, because I've banned them either indefinitely or I've banned them for life from our games.

"One individual I met only last week - and blocked him getting a ticket for the game and told him under no circumstances did I expect him to be there - he was there as well."

Bain said: "I think Osasuna showed they were inexperienced in handling a crowd of the magnitude that came.

"Yes, we only had 1,400 tickets, but we did make the authorities aware that when a club of this stature travels it brings fans in numbers."

Osasuna chief executive Angel Viscay: "We advised Rangers about possible segregation problems because of the lack of tickets. We told them we were going to give appropriate security for those 1400 travelling fans.

"It is not our fault the number increased incredibly. We cannot control them. I believe any accusation against Osasuna is out of order as we are not responsible for travelling fans.

"However, I want to point out the majority of Rangers fans behaved in an amicable way and only a few were badly behaved."
