Celtic will discover on Friday if they are to get a Europa League reprieve with chief executive Peter Lawwell believing they have a "very strong case".

The Parkhead club played both legs of their play-off defeat against Swiss side Sion under protest over their opponents' alleged breach of a transfer embargo. UEFA's control and disciplinary body will make a ruling although Sion having two rights of appeal.

"We think we have a very strong case and we have been told we will get a decision tonight," said Lawwell. "We played under protest in the two games because our strong view was that there were ineligible players. We followed that with a formal protest subsequent to the games and that is our position."

He added: "The SFA have been very supportive, they understand the arguments we have.

"You never know what will happen and I think we need to respect those that are making the judgement.

"We will now await that judgement."

Lawwell, though, acknowledged the complexities of the issue which he described as a possibly a "landmark case".

"It is a complicated case," he said.

"What you have here is the rules and regulations of football being challenged by a domestic court in Switzerland.

"Clearly there are a number of huge issues that could be thrown up in terms of registrations of players but there are other issues in terms of football regulations so it is a huge issue for FIFA. But we need to respect the processes that UEFA are going through."
