Interviewed by Kicker, Sir Alex Ferguson also talked about current Premier League campaign:
"Now It’s harder to predict winners than it was for many years. However, I think there’s five potential candidates. Manchester City are the most likely to win, you can Guardiola's hands in their football. Tottenham and Liverpool follow, but also Manchester United are still there, if we get some consistency soon. Even when you are trailing by six, eight points, it’s still possible to catch one or two teams. The rivalry and the experience of Guardiola and Mourinho makes for an exciting competition. And you shouldn’t forget Arsenal. The team now is more sturdy".
