Brighton defender Lewis Dunk is being chased by a trio of Premier League clubs, after Arsenal, Tottenham, and Manchester City scouts ran the rule over him at The Den on Tuesday evening skysports.com understands.
The 19-year-old has started the season alongside Seagulls skipper Gordon Greer at the heart of Gus Poyet's defence, and has blossomed beyond all recognition.
Gunners boss Arsene Wenger, who is looking to fix his defensive problems at the Emirates Stadium, sent chief scout Steve Rowley to the midweek Npower Championship fixture to run the rule over the talented stopper.
But Arsenal could face competition for his signature from north London rivals Tottenham, after coaching duo Joe Jordan and Clive Allen were also spotted in the Millwall stands.
Spurs boss Harry Redknapp is known to be in the market for a defender, having failed to agree a deal for Bolton's Gary Cahill in the summer.
And with Sebastien Bassong expected to leave White Hart Lane in Jauary, and Ledley King's continuing injury problems, Tottenham could move to bring in Dunk.
Manchester City are also believed to be monitoring the player's progress, but it is understood that Arsenal and Tottenham are the leading contenders and are set to compile a more detailed dossier ahead of respective January bids.
But Poyet has warned Dunk’s suitors it will take a big-money bid to tempt him to sell one of his prized assets.
"They will have to pay," he said. "Everybody has got a price and Dunky has got a price, because he is in the team and because of the way he is playing.
"Sometimes you can't keep players forever. If that happens and he is going to play in the Premier League that is something I cannot control."
