Sacked Birmingham City boss Lee Clark fears the club will struggle to keep hold of Koby Arthur and Demarai Gray.
Blues rejected a deadline day bid of £500,000 from Crystal Palace for Gray, who is also being linked with Liverpool.
"They (the supporters) have got to be excited about them, but worried," said Clark, in his last interview before he was sacked.
"There were about 12 Premier League clubs there on Saturday.
"We have already had a bid (for Gray) on deadline day.
"That's what worries me."
