Palacios, 30, has spent the past seven seasons in England after moving from Honduran club Olimpia to Wigan Athletic in January 2008 following a brief loan spell at Birmingham City, and enjoyed a fruitful stint with Tottenham Hotspur between 2009 and 2011.
However, the former £12 million man would struggle for both form and fitness following a £6 million switch to Stoke in August 2011, going on to make just 38 appearances in the Premier League over the next four campaigns.
Released last month after failing to make a first-team appearance during the 2014-15 campaign, the Honduras international is now on the hunt for a new challenge and MLS looks to be an option ahead of the league’s summer transfer window opening on 8 July.
While linked with Bolton earlier this month [h/t Stoke Sentinel], he has been training with the Union for over a week now and Curtin hinted that the club would be interested in a deal after admitting that the 95-times capped veteran has been impressing.
Speaking after Palacios was snapped on the training ground ahead of Monday’s press conference, the Philadelphia boss said: “Wilson’s been in with us for about a week. He’s done well. He is a guy who obviously, his career speaks for itself, at the international level, the World Cup, with Tottenham and Stoke.
“He’s a guy who has played at some big clubs. We had him in for the week to take a look at him. He’ll still be here through Wednesday and we’ll have to make a decision after that. But he’s been good.
“We’re always looking to upgrade our roster and have competition at every spot,” he added. “Just like any normal team right now, the window is about to open up in July and there will be some player movement, not only from our team, but from other teams in MLS.”
Things sound tentative at this point then but, judging from Curtin’s comments, it would be no surprise if Palacios was running out at PPL Park come next month.
