The SPL's Strategic Review Group met at Hampden today, where the issue of revamping Scottish football was discussed once again.

But Doncaster - who favours a move that would see the league cut to 10 teams and a second tier introduced - concedes that more talks will have to take place before a consensus for change is likely to be reached.

He told BBC Scotland: "Something of this depth is going to take a lot of discussion.

"We have an enormous hurdle to get over, which is 11 votes, and what we are dealing with is clubs who have their own domestic issues to concern themselves with.

"There remains enthusiasm for change and people find the bulk of what is in the plan very exciting.

"Unfortunately, it all comes down to one stumbling block, which is the size of the top league. We clearly need to engage further with the clubs that favour another plan. It's important that we all work together."

The 10-club proposal was the result of an SPL working party containing representatives from Aberdeen, Celtic, Hibernian, Motherwell, Rangers and St Mirren.

Hamilton chairman Ronnie McDonald also voiced his support for the proposal before the Lanarkshire club's relegation.

However, Dunfermline chairman John Yorkston - whose club has been promoted to the SPL next season - claimed earlier this week that the proposed move to a 10-team league was "now dead" after a meeting with representatives from eight of the 12 clubs at Tynecastle.

Celtic, Rangers, Aberdeen and Hibernian were not represented at those talks on Tuesday, where it was suggested that the possibility of a 14-team league should be reinvestigated.

Speaking after today's meeting, Aberdeen chairman Stewart Milne told STV: "I think there's still work to be done.

"I think there's a number of people becoming frustrated. I can't see any change for next season."

He added: "Fourteen teams was evaluated as part of the overall exercise and it was demonstrated clearly that it was not viable.

"It doesn't do anything on the football front and it doesn't do anything on a financial front. I don't think there'll ever be a 14-team league."
