Philadelphia Union head coach John Hackworth is all for sending young players to Europe for winter training spells.
Recently the club sent Michael Farfan, Amobi Okugo and Freddy Adu to join Zac MacMath, Cristhian Hernandez and Jimmy McLaughlin for training stints abroad and although Hackworth is fall for the experience, he admits he wants a balance for the promising group.
"We've set some parameters for all of our players and a time frame of when we allow them to seek out these opportunities and when we want them to shut it down and recover and regenerate from a very long season," Hackworth told MLSsoccer.com.
"They'll all be back soon and then they'll be on lockdown. Their job then is to recover mentally and physically, so we can really go after it in the start of the preseason.
"It's a delicate balance but for Amobi and for Michael, I feel very positive those guys can handle it."
Adu will head to Turkish giants Galatasaray whilst Farfan and Okugo will both be sent to German club SC Freiburg. MacMath is currently with Everton, Hernandez with Spain's Real Sociedad and McLaughlin is with Germany's Hoffenheim.
