Sources: Fabian Castillo closing in on Trabzonspor move

The Colombian midfielder's time with FC Dallas is coming to an end, as the 24-year-old is set for a move to the Turkish club.

Fabian Castillo has been eyeing a move to Europe for some time and though FC Dallas has aspirations of winning the club's first MLS Cup title, the Colombian winger doesn't want to stick around for that — making a transfer inevitable.

Castillo is on the verge of having his wish for a move granted. Dallas is putting the finishing touches on a sale to Turkish club Trabzonspor for a transfer fee in the neighborhood of $3 million to $4 million, sources confirmed to Goal USA on Friday.

Dallas is believed to have been weighing up a handful of offers for the 24-year-old, but Trabzonspor has emerged as the favorite for his services.

With five goals and five assists on the season, Castillo has been one of the key figures on a Dallas team currently boasting the best record in MLS. The Colombian has been previously linked to clubs in England and Spain. 

It now looks more likely he will be joining a Trabzonspor side that finished a disappointing 12th in the Turkish Super Lig in the 2015-16 season.

Castillo joined Dallas in 2011 from Deportivo Cali and has excelled with the MLS club, earning his first caps with the Colombian national team in 2015. FCD inked Castillo to a five-year contract in February 2015.
