Sir Alex Ferguson admits the Big Four's dominance is under threat from Man City, Spurs, Villa and Everton.
Man Utd, Chelsea, Liverpool and Arsenal have had things their own way since the 2004/05 season - but Fergie senses things might be about to change in the top flight.
Spurs, Villa and City are all currently above seventh-placed Liverpool in the table and the Old Trafford chief claims the race for Champions League football is wide open.
The Scot said: "I could toss a coin and that could be my best chance of deciding who could break into the top four out of Tottenham, Aston Villa, Everton and Manchester City with all the money they have.
"That's a difficult competition in itself and any one of them is capable of doing that."
He also told a League Managers' Association dinner: "I had a feeling about there being a change last season. The top teams are losing games and more points than ever through the early part of the season.
"That gives rise to the hope that it could be a very competitive league. But my experience tells me that two teams break away towards the last part of the season."
