MLS champions Real Salt Lake have signed Fabian Espindola for four years.

The Argentine striker will remain with the club until the end of the 2013 season in what RSL general manager Garth Lagerwey described as a major boost.

"We are excited to reach a long-term agreement with Fabian and are looking forward to seeing him in a Real Salt Lake uniform for the foreseeable future," said Lagerwey. "Fabian's talent and determination have been clearly evident over the last three seasons, and we are thrilled that he'll be a cornerstone of our attack as he enters the prime years of his career."
