Sir Alex Ferguson’s new book, ‘Leading’, is setting the news agenda just as his previous efforts did.

We have covered a number of revelations from the book, as well as a publicity event to promote it, on the main site on Tuesday.

[FERGIE: We wanted five other managers before Moyes]

[FERGIE: I only had four world-class players at United]

But Ferguson also offered lots of transfer titbits, discussing all the players he tried and failed to sign – deals which could have changed the course of football history as we know it.

Here are the seven most prominent targets who eluded Ferguson, and the reasons the deals fell through.

7. Petr Cech

6. Lucas Moura

4. Didier Drogba

“We went to check him out [when he played for Marseille] but the club wanted £25 million and Chelsea moved in for the kill before we had made up our minds.”

3. Thomas Muller
