Sydney FC have signed former American youth international Michael Enfield to a two-year contract.
The 23-year-old attacking midfielder, who was a fringe player at the Los Angeles Galaxy, has spent the past month on trial with the A-League club, impressing during Sydney's midweek trial matches against NSW Premier League clubs.
He is unable to play during the Asian Champions League group phase, but will be eligible to take part if Sydney reaches the knockout stages in September.
Enfield performed strongly for United States youth teams as a teenager, scoring seven times in a total of 14 appearances for the Under 18s and Under 20s.
He played college football for UCLA, before being drafted to the Galaxy in the US Major Soccer League in 2005. Enfield played 11 games for LA in 2005-06, scoring once, but was let go at the end of the season.
After arriving in Sydney last month, the California native scored on debut against the Wollongong Wolves before having a hand in all three Blues' goals versus Marconi Stallions last Wednesday.
"The club is delighted to have Michael on board for the next two seasons," said Sydney FC chief executive officer George Perry.
"He has made a big impact, both on and off the field, since arriving in the country."
Enfield said: "I am very thankful for the opportunity to play in a great city for a great club with great people."
