Capped once by Mali, Dicko began his career with French club Strasbourg before moving to England where he had a successful trial with Wigan Athletic. However, after just one League Cup appearance, the striker was loaned out to Blackpool for the second half of the 2011/12 season.
Dicko found himself back at Bloomfield Road, again on loan, at the start of the 2012/13 campaign before further loan moves to Wolverhampton Wanderers and Rotherham United followed.
Eventually, Dicko found a permanent home with Wolves and it was during his time at Molineux that he found his best form, hitting 13 goals in 19 appearances to fire his new side to the League One title in 2014.
He continued to find the net with regularity in the Championship, scoring 15 times in Wolves’ first season back at that level, but injury meant that his 2015/16 campaign didn’t move beyond September.
After a long lay-off, his form began to return towards the end of 2016/17 and it was a goal scored against the Tigers in the early weeks of 2017/18 that prompted Leonid Slutsky to bring the forward to East Yorkshire.
