Tobol, who ended as runners-up to Kairat in the Kazakhstani top-flight last season, have completed the signing of Guinea-Bissau international Silva on a season-long deal for the 2021 campaign.
The 27-year-old joins the club on a free transfer after leaving fellow KPL side FC Taraz at the end of the 2020 season, having scored four goals in 17 appearances for his former side.
Dennis Lota (Zambia) – The late 'Chesa Mpama' scored 74 goals in his PSL career and still holds the record for the most goals scored in a single season at Orlando Pirates (23).
Jean-Marc Ithier (Mauritius) - He was 34 when he came to the PSL and still reached double figures in each of his first five seasons, scoring 71 goals in total for Santos.
Wilfred Mugeyi (Zimbabwe) - 'Silver Fox' top-scored with 23 goals in the 1996/97 season and scored 91 times in the PSL era. He scored 113 for Bush Bucks including pre-96 goals.
