"JDT would like to wish Safawi Rasid all the best as he leaves for Portuguese Primeira Liga side Portimonense SC tonight.
"Safawi has been an excellent servant to the Southern Tigers since his debut on 27 January 2017. The 23-year-old has made 101 appearances for JDT, notching 47 goals and 18 assists.
"Safawi has won four Malaysia Super League titles, two Malaysia Cups and three Charity Cups with the Southern Tigers," posted the Johor side on social media.
Selamat Maju Jaya kepada Safawi. Saya berdoa semoga anda berjaya. Pintu kelab JDT sentiasa terbuka untuk Safawi. This is not the end, it's only the beginning.
