There's only one Fergie (but Alex has seen 193 rival bosses in 23 years)

ONE Alex Ferguson, there’s only one Sir Alex Ferguson.

But in the 23 years since the Scot took over as Manchester United boss there have been no fewer than 193 managers at the 19 other clubs currently in the Premier League.

And that’s not counting all the caretakers left holding the reins from time to time.

While other clubs chop and change coaches at the drop of a point, their combined efforts in the silverware stakes barely surpass the groaning shelves of the Old Trafford trophy room since fiery Sir Alex’s arrival in 1986.

Phil Scolari at Chelsea is just the latest big name to be blown away in his slipstream.

Only Arsenal have shown anything like as much loyalty to managers as United since November 1986, and that has been reflected in the amount of silverware they have won.

Chelsea’s glory has been largely confined to a glut of trophies in the Mourinho years, while Liverpool’s European triumph cannot disguise their poor League showing.

Football’s big 4? No, just the Big 1 — the one Alex Ferguson.
