Bobby Robson’s managerial career spanned four countries, one international job and saw him win 11 major honours – and reach a World Cup semi-final with England (what we’d give for that today).
Sir Bobby’s influence stretches far and wide, no more so than in the managers prowling the touchlines of Europe in the modern game.
A chart unearthed by FootySuperTips shows just how important the ex-Barcelona and England boss was.
Not only are Jose Mourinho and Pep Guardiola the twin footballing sons of Sir Bobby (both worked with him at Barcelona and Mourinho was his Porto assistant), but there are even links to Brendan Rogers, André Villas-Boas, Laurent Blanc and Luis Enrique and Tito Vilanova.
Sir Bobby Robson's coaching tree.

All of these names either played under Robson or worked under him as coaches, scouts or youth team staff.
The impressive roster also boasts, err, some less than stellar managerial careers. Stuart Pearce and Peter Reid played under Robson for England and both went on to manage at Manchester City, while Pearce took the England under-21s to a tournament final and had a short-lived spell back at Nottingham Forest.
Mercifully, Alan Shearer’s 8-game managerial run at Newcastle doesn’t earn him a place on the list.
When you’re sitting down to watch the next Manchester derby showdown between Jose and Pep, it’s worth remembering that none of this would’ve happened had it not been for Robson.
There’s no mentor quite like him.
