He has already brought seven players through the door at Ibrox, and it appears an eighth signing is on the horizon, with Roma forward Sadiq expected to be signed ahead of Rangers' maiden voyage into Europe in this campaign on Thursday evening.
The Gers tied up a permanent deal for Jamie Murphy following a successful loan spell from Brighton and Hove Albion, and then set about adding new faces to the squad.
After a series of good performances for Roma's youth side, he broke into the first team at the age of 18 in November 2015, scoring his first senior goal two months later.
Sadiq was part of Nigeria's U-23 team that won bronze medal in the football event at the Rio 2016 Olympics.

New signing Lassana Coulibaly was anxious he was the victim of a prank call when Rangers boss Steven Gerrard phoned to discuss a move to Ibrox. I got a phone call from my agent and he told me about Rangers and I said let's see what happens.
"He called me about two weeks ago and from there I started changing my mind". When he was at Liverpool, I grew up watching him.
"When they asked me if I want to join this team or not, I said yes but I thought it might not really be Gerrard!"
He told me about the team, the players, that everyone will be at my side if I come here and he will help me to go forward in my career. I don't watch the league, but I know about Celtic and Rangers in Scotland.
"We didn't talk that much about how the team or I would play it was all just Rangers, Rangers, and Rangers".
