Reports today suggest one of the proposals under discussion includes increasing the number of top-flight clubs from 12 to 14 from the season after next, with relegation play-offs featuring in the new set-up.

An SPL spokesman told Press Association Sport: "Our chairman and chief executive are discussing league reconstruction with our clubs at the moment but it is too early to draw any firm conclusions from that work.

"It is fair to say that a number of different league formats are being reviewed as part of that process.

"It is our job to try and build a consensus across our clubs first and then with others in Scottish football."

The format reportedly under consideration would see clubs play each other twice before the division split into a top six and bottom eight after 26 games.

After the split, clubs would play each other home and away, meaning 36 games for those in the top six and 40 for those finishing in the bottom eight.

One club would be automatically relegated from the SPL and one promoted from the Irn-Bru First Division.

The second-bottom SPL club would then be involved in a play-off with the teams finishing second, third and possibly fourth in the First Division.

At present, the SPL splits into two sections of six after 33 games, with only one club relegated.

This often leads to an imbalance of home and away fixtures for certain clubs, something which has been widely criticised.

SPL clubs are due to meet at the end of the season for a strategy day.

This is set to see various proposals for league reform discussed, including expansion to 16 or 18 teams.

Any change to the current league set-up requires an 11-1 vote in favour from the existing 12 SPL clubs.

Celtic`s interim boss Neil Lennon would support any plans to increase the size of the SPL by two teams.

He said: "I would back it. It needs change.

"Adding two teams wouldn't over-dilute things and I think players and coaches are looking for a wee bit more variety."

Rangers assistant manager Ally McCoist believes the current league format provides excitement but concedes it may not be ideal for the future of the Scottish game.

"I'm not as pessimistic as everyone else," he said.

"Effectively, what the league has done and continues to do right up until now, is provide excitement, whether it's qualification for Europe, relegation.

"You can't argue against the fact that there is still excitement going on in the SPL.

"You could certainly make an argument and say it's not the best league in the world but, the way they have structured it at the moment, we are getting the best out of the league.

"Are we are getting the best out of the teams and the best out of Scottish football? I'm not so sure.

"Me sitting here and giving you an answer isn't going to do anything. We have to sit down round a table and get the opinion of everybody who matters."
