CELTIC have been warned they might miss out on Derry City striker Michael Duffy.
The 20-year-old frontman, who has impressed in two trial periods at the champions, is now on Brentford’s wanted list.
Duffy and his Derry team-mate Patrick McEleney are being put through their paces this week by the Championship side whose assistant boss is former Rangers skipper Davie Weir.
The £300,000-rated attacker netted twice against Dutch World Cup keeper Tim Krul in a closed-door game at Newcastle a fortnight ago.
He was hopeful of clinching a move to the Hoops, but no offer has been made.
Sean Barrett, the Irish club’s chief executive, said: “Michael has gone to Brentford and they’re playing Wolves tomorrow in a development game.
“Brentford have been monitoring both our players for a while.
“We’ve heard nothing concrete from Celtic.”
Barrett added: “Celtic monitored Michael for four or five games last season.
“He got glowing reports from his first trial and from fitness tests and they wanted him over to play a game.
“He then plays in a match, scores two goals against Newcastle and that, too, against Tim Krul. What more can he do?
“He’s obviously disappointed as he’s done all they asked of him.
“If Celtic are interested then they should make a move for him now.
“I think they should make an offer because there are other clubs interested in him.
“Celtic risk losing him if they don’t go for him. Now is the time.”
