The Portuguese has not yet arrived at Villa's Bodymoor Heath training ground, and McLeish had been hoping to keep the move quiet. However, any hopes of so doing were extinguished when Djalo resorted to social media, something the Villa boss is clearly disappointed with.
"We're just going to look at him on trial," McLeish said. "Talk of signing him is very premature. I didn't really want it to be anybody's business, but I know the lad put it on Facebook himself, so what chance have you got?"
Djalo is currently in contractual limbo at French side Nice. He joined the French side on the last day of the summer transfer window from Sporting Lisbon, but FIFA rejected the move after league officials only registered his documents after midnight when the market was closed.
McLeish was cagey when asked about Djalo's qualities as a footballer.
He said: "I can't tell you anything about him just now. I don't want to divulge anything. Look him up on Google."
Fans got wind of the deal after Djalo posted 'I go to Aston Villa' on his Facebook page.
McLeish hinted he may go down a similar route with other players when trying to strengthen his squad, as a modest budget means he must remove as much risk as possible from his transfer dealings.
"We'll quietly look at people when we get an opportunity. There's others that are out there as well. We want to try and do things carefully and prudently, and we'll continue to do so," he said.
