It may take new Rangers to recruit Amad Diallo for up to eight games to reach full match fitness.
That is the view of injury expert Ben Dinnery, who runs the Premier Injuries site and has a background in medicine and data analysis.
Diallo, who signed on loan from Man United last month, scored four minutes into his debut against Ross County last Saturday (29 January).
But he was taken off with 25 minutes to go at Victoria Park and was also hooked at half-time in the 3-0 humiliation at Celtic last night (2 January).
Per the Metro after the 3-3 draw with Ross County, Giovani van Bronckhorst confessed: “We had to take him off because he didn’t have the rhythm.”
Dinnery suggests that it could take the 19-year-old winger several weeks to reach pick physical output at Ibrox.
“It’s a big step up,” he told Football Insider‘s Adam Williams.
“Under 23s and Premier League 2 is great but that step to competitive football is always going to need some acclimatisation.
“It’s a different league but he’s a young lad and I understand he works really well on and off the pitch.
“He wants to go there and make an impression. He will know that the likes of Ralf Rangnick will be watching closely.
“Van Bronckhorst is a manager who has great pedigree off the pitch and can give him excellent guidance.
“There is going to be an element of wanting to go out and impress his new boss there.
“But it’s as much about understanding the team’s philosophy and setup as it is about rhythm.
“You haven’t really got the time or luxury to bring him in gently. You need him to hit the ground running.
Typically, it could be four to six or even eight games before they start to get that sharpness and understanding.
“After that, we should see a player who is approaching a good level of fitness.”
