The Magpies legend was drafted in for the final eight games of the 2008/09 season but was unable to prevent the club from Premier League relegation.
And while it didn’t end well, it didn’t start well either. Click through the pages to see where the starting XI Shearer named that day are now:
5. Jose Enrique
The Spaniard was forced into early retirement in 2017 due to a persistent knee problem before being diagnosed with a brain tumour. A year on from his diagnosis, Enrique thankfully received the all-clear in April 2019. Photo: Clive Mason
6. Jonas Gutierrez
United’s very own superhero for several different reasons. Gutierrez has suffered two serious knee injuries in the last two years but the 36-year-old is determined to keep playing in Argentina, whether that be at current club Banfield or elsewhere. Photo: Clive Mason
7. Kevin Nolan
Nolan, after trying his hand in management with Leyton Orient and Notts County - who he guided to the League Two play-offs - is back in the Premier League as a first team coach under David Moyes at West Ham United. Photo: ANDREW YATES
8. Nicky Butt
The 45-year-old is back at Manchester United as head coach of their youth academy. However, it isn't just on-field matters Butt deals with - he co-owns League Two side Salford City alongside other members of the ‘Class of 92’. Photo: Laurence Griffiths
