'Last time we had a club we could believe in': Newcastle United fans pay tribute to Sir Bobby Robson
Robson managed the Magpies between 1999 and 2004 and guided the club to successive top four finishes in the Premier League.
The former England and Barcelona boss died of lung cancer in 2009 after making a lasting impression on many people in the game.
Here are some of the messages from Newcastle fans praising their former boss.
