Manchester City chief executive Garry Cook can't predict when they will break even, despite the Uefa president Michel Platini's proposal that clubs who fail to balance their books within three years will be barred from European competition.

The European Club Association backs Platini's proposals that clubs who fail to do so will be excluded from Europe.

"You can't predict the wage base," Cook told the Independent on Sunday. "From a business standpoint it's not the smartest thing to start to predict long-term financial profit and loss statements. That's not lack of discipline or naivety - that's the reality of a business model which is a moving target. It's foolish to put a line in the sand and predict dates by which you break even."

City, Cook indicated, will lobby through the Premier League against any plans which create a disincentive to prospective foreign investors.

"We should always allow investment in the Premier League. It's the greatest league in the world - a truly global entity - and we should always allow that investment, as long as everybody manages the integrity and the Premier League puts governance in place to control who [invests] and how."
