Alan Shearer admitted Newcastle United had made 'big mistakes' and ultimately were not good enough to survive after their relegation was confirmed.
The Magpies' 16-year stay in the top-flight came to an end after they lost 1-0 at Aston Villa on the final day of the season, to let both Hull City and north-east rivals Sunderland off the relegation hook.
Interim manager Shearer refused to discuss his future after the final whistle, but pulled no punches when asked if relegation had been cruel on his hometown club.
"I can't complain, we weren't good enough over the 38 games," said the Magpies' all-time leading goalscorer, who won just one of his eight games at the helm since replacing Joe Kinnear in the hot-seat.
"It's what's in the dressing room that hasn't been good enough.
"Congratulations to the other teams who have stayed up.
"They will build in the Premier League and this club will have to build to get back up.
"There's big changes needed to be made, from top to bottom. Big mistakes have been made."
When asked about his own future, he added: "Ask me that in a few days. I haven't even thought about it.
"First and foremost I haven't been offered it and I haven't thought about it.
"It's a magnificent football club, you've seen our following today. They deserve better than we've given them all season."
