Newcastle manager Rafael Benitez must be given funds to improve the team before they return to the Premier League next season, says Alan Shearer.
Benitez, 57, spent more than £50m last summer, but Shearer says Newcastle risk losing the Spaniard if he is not backed again financially by owner Mike Ashley.
"I would think giving him transfer funds would be key to keeping hold of him," the ex-Newcastle striker said.
The Magpies sealed promotion with a 4-1 home win over Preston on Monday.
Shearer, the club's all-time leading scorer continued to BBC Radio 5 live: "He's a huge figure at the club, he loves the place and the passion of fans, and it's hugely important Newcastle keep hold of him.
