Newcastle boss Eddie Howe says he hopes the prospect of losing another talent like Ivan Toney won't be repeated.
The Brentford striker, 26, is celebrating his maiden England call-up this week, four years after being sold by Newcastle to Peterborough for just £300,000.
Howe said: "I'd love to think that (Toney situation) would not happen now. That's not a criticism of anyone at that time and why Ivan left, I don't know.
"When you watch him play now and see his attributes and what he can bring to his team, he's an outstanding player.
"The call-up is a great thing for players who go to the lower leagues and gives them hope it's not the end of their dreams. He's had to work his way back up and he's done incredibly well."
Meanwhile, Callum Wilson is likely to miss Saturday's visit of his former club Bournemouth and, having previously stated his ambition to win a place in England's World Cup squad, those hopes would appear remote given his injury and the emergence of Toney. Howe disagrees.
"Never write off Callum Wilson, his mindset is incredible," said Howe, who is set to be without hamstring-victim Allan Saint-Maximin this weekend but will welcome back Bruno Guimaraes.
"I don't think Callum's World Cup chance is gone, and I don't think he believes so either. For Callum, you can't sit there and dwell and go, 'Poor me'.
"He's had an unbelievable rise himself from non-league to the position that he's in. He savours every moment rather than look at negative situations. It will just fuel his motivation, it will fire him even more so when he returns to show how good he is."
